Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Horizon Global Corporation (“Horizon,” “Horizon Global,” or the “Company”) is a global designer, manufacturer and distributor of a wide variety of high quality, custom-engineered towing, trailering, cargo management and other related accessories. These products are designed to support original equipment manufacturers and original equipment suppliers (collectively, “OEs”), aftermarket and retail customers within the agricultural, automotive, construction, horse/livestock, industrial, marine, military, recreational, trailer and utility markets. The Company groups its operating segments into reportable segments by the region in which sales and manufacturing efforts are focused. The Company’s reportable segments are Horizon Americas, Horizon Europe-Africa, and Horizon Asia-Pacific. See Note 9 , “ Segment Information ,” for further information on each of the Company’s reportable segments. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016 . Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. It is management’s opinion that these financial statements contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Results of operations for interim periods are not necessarily indicative of results for the full year.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also modifies the accounting for components excluded from the assessment of hedge effectiveness, eases documentation and assessment requirements and modifies certain disclosure requirements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted and should be applied on a modified retrospective basis. The Company is in the process of assessing the impact of the adoption of ASU 2017-12 on its condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 eliminates the requirement to perform a hypothetical purchase price allocation to measure the amount of goodwill impairment. Instead, under ASU 2017-04, the goodwill impairment would be the amount by which a reporting unit’s carrying value exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. ASU 2017-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019 with early adoption permitted. The Company intends to early adopt ASU 2017-04 for its annual goodwill impairment test during the fourth quarter of 2017. In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory” (“ASU 2016-16”). ASU 2016-16 provides an amendment to the accounting guidance related to the recognition of income tax consequences of an intra-entity transfer of an asset other than inventory. This guidance is effective for public entities for fiscal years beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted the first interim period of a fiscal year and should be applied on a modified retrospective basis. Under the new guidance, an entity is required to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Under the current guidance, the income tax effects are deferred until the asset has been sold to an outside party. The Company does not expect the adoption of ASU 2016-16 to have a material impact on its condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which supersedes the leases requirements in “Leases (Topic 840).” The objective of this update is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. The Company is in the process of assessing the impact of the adoption of ASU 2016-02 on its condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” This guidance provides that inventory not measured using the last-in, first out (“LIFO”) or retail inventory methods should be measured at the lower of cost and net realizable value. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory. As of January 1, 2017, the provisions of this ASU became effective for the Company on a prospective basis and did not have a material impact on the Company’s condensed consolidated financial position or results of operations. Accounting Standards Update 2014-09 In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” This ASU supersedes most of the existing guidance on revenue recognition in ASC Topic 605, “Revenue Recognition”, and establishes a broad principle that would require an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity identifies the contract with a customer, identifies the separate performance obligations in the contract, determines the transaction price, allocates the transaction price to the separate performance obligations and recognizes revenue when each separate performance obligation is satisfied. The FASB has subsequently issued additional ASUs to clarify certain elements of the new revenue recognition guidance. This guidance is effective for Horizon Global beginning on January 1, 2018 and entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. The Company expects to adopt the ASU using the modified retrospective approach, which would result in a cumulative-effect adjustment as of the date of adoption. While Horizon Global is continuing to assess all potential impacts of implementing this guidance, the Company does not believe this standard will have a material impact on its condensed consolidated financial statements. There are also certain considerations related to internal control over financial reporting that are associated with implementing the new guidance under Topic 606. The Company is currently evaluating its control framework for revenue recognition and identifying any changes that may need to be made in response to the new guidance. Disclosure requirements under the new guidance in Topic 606 have been significantly expanded in comparison to the disclosure requirements under the current guidance. Designing and implementing the appropriate controls over gathering and reporting the information required under Topic 606 is currently in process.

The Convertible Notes are convertible at the option of the holder (i) during any calendar quarter beginning after March 31, 2017, if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business days after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Convertible Notes for each trading day of such period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (iii) upon the occurrence of specified corporate events; and (iv) on or after January 1, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date. During the third quarter of 2017, no conditions allowing holders of the Convertible Notes to convert have been met. Therefore, the Convertible Notes are not convertible during the fourth quarter of 2017 and are classified as long-term debt. Should conditions allowing holders of the Convertible Notes to convert be met in the fourth quarter of 2017 or a future quarter, the Convertible Notes will be convertible at their holders’ option during the immediately following quarter. As of September 30, 2017 , the if-converted value of the Convertible Notes did not exceed the principal value of those Convertible Notes. Upon conversion by the holders, the Company may elect to settle such conversion in shares of its common stock, cash, or a combination thereof. Because the Company may elect to settle conversion in cash, the Company separated the Convertible Notes into their liability and equity components by allocating the issuance proceeds to each of those components in accordance with Accounting Standards Codification (“ASC”) 470-20, “Debt-Debt with Conversion and Other Options.” The Company first determined the fair value of the liability component by estimating the value of a similar liability that does not have an associated equity component. The Company then deducted that amount from the issuance proceeds to arrive at a residual amount, which represents the equity component. The Company accounted for the equity component as a debt discount (with an offset to paid-in capital in excess of par value). The debt discount created by the equity component is being amortized as additional non-cash interest expense using the effective interest method over the contractual term of the Convertible Notes ending on July 1, 2022. The Company allocated offering costs of $4.0 million to the debt and equity components in proportion to the allocation of proceeds to the components, treating them as debt issuance costs and equity issuance costs, respectively. The debt issuance costs of $3.0 million are being amortized as additional non-cash interest expense using the effective interest method over the contractual term of the Convertible Notes. The Company presents debt issuance costs as a direct deduction from the carrying value of the liability component. The carrying value of the liability component at September 30, 2017 , was $93.8 million , including total unamortized debt discount and debt issuance costs of $31.2 million . The $1.0 million portion of offering costs allocated to equity issuance costs was charged to paid-in capital. The carrying amount of the equity component was $19.7 million at September 30, 2017 , net of issuance costs and taxes. Interest expense recognized relating to the contractual interest coupon, amortization of debt discount and amortization of debt issuance costs on the Convertible Notes included in the accompanying condensed consolidated statements of income are as follows: Three months ended Nine months ended 2017 2016 2017 2016 (dollars in thousands) Contractual interest coupon on convertible debt $ 880 $ — $ 2,310 $ — Amortization of debt issuance costs $ 130 $ — $ 350 $ — Amortization of "equity discount" related to debt $ 1,190 $ — $ 3,180 $ — In connection with the issuance of the Convertible Notes, the Company entered into convertible note hedge transactions (the “Convertible Note Hedges”) in privately negotiated transactions with certain of the underwriters or their affiliates (in this capacity, the “option counterparties”). The Convertible Note Hedges provide the Company with the option to acquire, on a net settlement basis, 5,005,000 shares of its common stock, which is equal to the number of shares of common stock that notionally underlie the Convertible Notes, at a strike price of $24.98 , which corresponds to the conversion price of the Convertible Notes. The Convertible Note Hedges have an expiration date that is the same as the maturity date of the Convertible Notes, subject to earlier exercise. The Convertible Note Hedges have customary anti-dilution provisions similar to the Convertible Notes. The Convertible Note Hedges have a default settlement method of net-share settlement but may be settled in cash or shares, depending on the Company’s method of settlement for conversion of the corresponding Convertible Notes. If the Company exercises the Convertible Note Hedges, the shares of common stock it will receive from the option counterparties to the Convertible Note Hedges will cover the shares of common stock that it would be required to deliver to the holders of the converted Convertible Notes in excess of the principal amount thereof. The aggregate cost of the Convertible Note Hedges was $29.0 million (or $7.5 million net of the total proceeds from the Warrants sold, as discussed below), before the allocation of issuance costs of approximately $0.7 million . The Convertible Note Hedges are accounted for as equity transactions in accordance with ASC 815-40 , “Derivatives and Hedging-Contracts in Entity’s own Equity.” In connection with the issuance of the Convertible Notes, the Company also sold net-share-settled warrants (the “Warrants”) in privately negotiated transactions with the option counterparties for the purchase of up to 5,005,000 shares of its common stock at a strike price of $29.60 per share, for total proceeds of $21.5 million . The Company also recorded the Warrants within shareholders’ equity in accordance with ASC 815-40. The Warrants have customary anti-dilution provisions similar to the Convertible Notes. As a result of the issuance of the Warrants, the Company will experience dilution to its diluted earnings per share if its average closing stock price exceeds $29.60 for any fiscal quarter. The Warrants expire on various dates from October 2022 through February 2023 and must be net-settled in shares of the Company’s common stock. Therefore, upon exercise of the Warrants, the Company will issue shares of its common stock to the purchasers of the Warrants that represent the value by which the price of the common stock exceeds the strike price stipulated within the particular warrant agreement. ABL Facility On December 22, 2015, the Company entered into an amended and restated loan agreement among the Company, Cequent Performance Products, Inc. (“Cequent Performance”), Cequent Consumer Products, Inc. (“Cequent Consumer”), Cequent UK Limited, Cequent Towing Products of Canada Ltd., certain other subsidiaries of the Company party thereto as guarantors, the lenders party thereto and Bank of America, N.A., as agent for the lenders (the “ABL Loan Agreement”), under which the lenders party thereto agreed to provide the Company and certain of its subsidiaries with a committed asset-based revolving credit facility (the “ABL Facility”) providing for revolving loans up to an aggregate principal amount of $99.0 million . The ABL Loan Agreement provides for the increase of the U.S. sub-facility from an aggregate principal amount of $85.0 million to up to $94.0 million (subject to availability under a U.S.-specific borrowing base) (the “U.S. Facility”), and the establishment of two new sub-facilities, (i) a Canadian sub-facility, in an aggregate principal amount of up to $2.0 million (subject to availability under a Canadian-specific borrowing base) (the “Canadian Facility”), and (ii) a U.K. sub-facility in an aggregate principal amount of up to $3.0 million (subject to availability under a U.K.-specific borrowing base) (the “U.K. Facility”). The ABL Facility also includes a $20.0 million letter of credit sub-facility, which matures on June 30, 2020. Borrowings under the ABL Facility bear interest, at the Company’s election, at either (i) the Base Rate (as defined per the credit agreement, the “Base Rate”) plus the Applicable Margin (as defined per the credit agreement “Applicable Margin”), or (ii) the London Interbank Offered Rate (“LIBOR”) plus the Applicable Margin. The Company incurs fees with respect to the ABL Facility, including (i) an unused line fee of 0.25% times the amount by which the revolver commitments exceed the average daily revolver usage during any month, (ii) facility fees equal to the applicable margin in effect for LIBOR revolving loans, as defined per the credit agreement, times the average daily stated amount of letters of credit, (iii) a fronting fee equal to 0.125% per annum on the stated amount of each letter of credit, and (iv) customary administrative fees. All of the indebtedness of the U.S. Facility is and will be guaranteed by the Company’s existing and future material domestic subsidiaries and is and will be secured by substantially all of the assets of the Company and such guarantors. In connection with the ABL Loan Agreement, Cequent Performance and certain other subsidiaries of the Company party to the ABL Loan Agreement entered into a foreign facility guarantee and collateral agreement (the “Foreign Collateral Agreement”) in order to secure and guarantee the obligation under the Canadian Facility and the U.K. Facility. Under the Foreign Collateral Agreement, Cequent Performance and the other subsidiaries of the Company party thereto granted a lien on certain of their assets to Bank of America, N.A., as the agent for the lenders and other secured parties under the Canadian Facility and U.K. Facility. The ABL Loan Agreement contains customary negative covenants, and does not include any financial maintenance covenants other than a springing minimum fixed charge coverage ratio of at least 1.00 to 1.00 on a trailing twelve-month basis, which will be tested only upon the occurrence of an event of default or certain other conditions as specified in the agreement. At September 30, 2017 , the Company was in compliance with its financial covenants contained in the ABL Facility. Debt issuance costs of approximately $2.5 million were incurred in connection with the entry into and amendment of the ABL Facility. These debt issuance costs will be amortized into interest expense over the contractual term of the loan. The Company recognized approximately $0.1 million and $0.4 million of amortization of debt issuance costs for the three and nine months ended September 30, 2017 , respectively, and approximately $0.1 million and $0.4 million for the three and nine months ended September 30, 2016 , respectively, which are included in the accompanying condensed consolidated statements of income. There were $1.4 million and $1.8 million of unamortized debt issuance costs included in other assets in the accompanying condensed consolidated balance sheets as of September 30, 2017 and December 31, 2016 , respectively. As of September 30, 2017 , there was $20.0 million outstanding under the ABL Facility with a weighted average interest rate of 3.2% . As of December 31, 2016 , there were no amounts outstanding under the ABL Facility. Total letters of credit issued were approximately $6.3 million and $7.0 million at September 30, 2017 and December 31, 2016 , respectively. The Company had $65.0 million and $68.7 million in availability under the ABL Facility as of September 30, 2017 and December 31, 2016 , respectively. Term Loan On June 30, 2015, the Company entered into a term loan agreement (“Original Term B Loan”) under which the Company borrowed an aggregate of $200.0 million , which matures on June 30, 2021. On September 19, 2016, the Company entered into the First Amendment to the Original Term B Loan (“Term Loan Amendment”), which amended the original Term B Loan to provide for incremental commitments in an aggregate principal amount of $152.0 million (“Incremental Term Loans”) that were extended to the Company on October 3, 2016. The Original Term B Loan and Incremental Term Loans are collectively referred to as “Term B Loan”. On March 31, 2017, the Company entered into the Third Amendment to the Term B Loan (the “Replacement Term Loan Amendment”), which amended the Term B Loan to provide for a new term loan commitment (the “Replacement Term Loan”). The proceeds from the Replacement Term Loan were used to repay in full the outstanding principal amount of the Term B Loan. As a result of the Replacement Term Loan Amendment, the interest rate was reduced by 1.5% per annum. Additionally, quarterly principal payments required under the Original Term B Loan and Term Loan Amendment of $2.5 million and $2.1 million , respectively, were reduced to an aggregate quarterly principal payment of $1.9 million . On and after the Replacement Term Loan Amendment effective date, each reference to “Term B Loan” is deemed to be a reference to the Replacement Term Loan. The Term B Loan permits the Company to request incremental term loan facilities, subject to certain conditions, in an aggregate principal amount, together with the aggregate principal amount of incremental equivalent debt incurred by the Company, of up to $75.0 million , plus an additional amount such that the Company’s pro forma first lien net leverage ratio (as defined in the term loan agreement) would not exceed 3.50 to 1.00 as a result of the incurrence thereof. Borrowings under the Term B Loan bear interest, at the Company’s election, at either (i) the Base Rate plus 3.5% per annum, or (ii) LIBOR, with a 1% floor, plus 4.5% per annum. Principal payments required under the Term B Loan are $1.9 million due each calendar quarter beginning June 2017. Commencing with the fiscal year ending December 31, 2017, and for each fiscal year thereafter, the Company will also be required to make prepayments of outstanding amounts under the Term B Loan in an amount up to 50.0% of the Company’s excess cash flow for such fiscal year, as defined in the Term B Loan, subject to adjustments based on the Company’s leverage ratio and optional prepayments of term loans and certain other indebtedness. All of the indebtedness under the Term B Loan is and will be guaranteed by the Company’s existing and future material domestic subsidiaries and is and will be secured by substantially all of the assets of the Company and such guarantors. The Term B Loan contains customary negative covenants, and also contains a financial maintenance covenant which requires the Company to maintain a net leverage ratio not exceeding 5.25 to 1.00 through the fiscal quarter ending September 30, 2017, 5.00 to 1.00 through the fiscal quarter ending March 31, 2018, 4.75 to 1.00 through the fiscal quarter ending September 30, 2018; and thereafter, 4.50 to 1.00 . At September 30, 2017 , the Company was in compliance with its financial covenants in the Term B Loan. During the first quarter of 2017, the Company used a portion of the net proceeds from the Convertible Notes offering as described above, along with proceeds from the Common Stock Offering as described in Note 11 , “Earnings per Share” , to prepay a total of $177.0 million of the Term B Loan. In accordance with ASC 470, “Debt - Modifications and Extinguishments”, the prepayment was determined to be an extinguishment of the existing debt. As a result, the pro-rata share of the unamortized debt issuance costs and original issuance discount related to the prepayment, aggregating to $4.6 million , was recorded as a loss on the extinguishment of debt in the condensed consolidated statements of income. The remaining unamortized debt issuance costs and original issuance discount, including $2.4 million additional transactions fees incurred in connection to the Replacement Term Loan Amendment, was approximately $6.1 million . Both the aggregate debt issuance costs and the original issue discount will be amortized into interest expense over the remaining life of the Term B Loan. The Company recognized approximately $0.4 million and $1.2 million of amortization of debt issuance cost and original issue discount for the three and nine months ended September 30, 2017 , respectively, and $0.3 million and $1.0 million for the three and nine months ended September 30, 2016 , respectively, which is included in the accompanying condensed consolidated statements of income. The Company had an aggregate principal amount outstanding of $151.6 million and $337.0 million as of September 30, 2017 and December 31, 2016 , respectively, under the Term B Loan bearing interest at 5.7% and 7.0% , respectively. The Company had $5.3 million and $8.7 million as of September 30, 2017 and December 31, 2016 , respectively, of unamortized debt issuance costs and original issue discount, all of which are recorded as a reduction of the debt balance on the Company’s condensed consolidated balance sheets. The Company’s Term B Loan traded at approximately 101.4% and 101.6% of par value as of September 30, 2017 and December 31, 2016 , respectively. The valuation of the Term B Loan was determined based on Level 2 inputs under the fair value hierarchy. Bank facilities Our Australian subsidiaries were party to a revolving debt facility with a borrowing capacity of approximately $11.7 million , which would mature on November 30, 2017 , that was subject to interest at a bank-specified rate plus 1.9% and was secured by substantially all the assets of the subsidiary. No amounts were outstanding as of December 31, 2016 under this facility. On July 3, 2017, our Australian subsidiaries entered into a new agreement (collectively, the “Australian Loans”) to provide for revolving borrowings with an aggregate principal amount of $32.0 million as of September 30, 2017 . The Australian Loans include two sub-facilities: (i) Facility A , with a borrowing capacity of $20.3 million that matures on July 3, 2020 and (ii) Facility B , with a borrowing capacity of $11.7 million that matures on July 3, 2018 . No amounts were outstanding as of September 30, 2017 under the Australian Loans. Borrowings under Facility A bear interest at the Bank Bill Swap Bid Rate (“BBSY”) plus a margin determined based on the most recent net leverage ratio (as defined per the Australian credit agreement). The margin is to be determined on the first day of the period as follows: (i) 1.10% per annum if the net leverage ratio is less than 1.50 to 1.00; (ii) 1.20% per annum if the net leverage ratio is less than 2.00 to 1.00 and (iii) 1.30% if the net leverage ratio is less than 2.50 to 1.00. Borrowings under Facility B bear interest at the BBSY plus a margin of 0.9% per annum. The Australian Loans contain financial covenants, which require our Australian subsidiaries to maintain: (i) a net leverage ratio not exceeding 2.50 to 1.00 during the period commencing on the date of the agreement and ending on the first anniversary of the date of the agreement; and 2.00 to 1.00 thereafter; (ii) a working capital coverage ratio (as defined per the Australian credit agreement) greater than 1.75 to 1.00 at all times; and (iii) a gearing ratio (defined as the ratio of senior debt to senior debt plus equity) not to exceed 50% .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Foreign Currency Exchange Rate Risk As of September 30, 2017 , the Company was party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $17.2 million . The Company uses foreign currency forward contracts to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to certain payments for contract manufacturing in its lower-cost manufacturing facilities. The foreign currency forward contracts hedge currency exposure between the Mexican peso and the U.S. dollar, the Thai baht and the Australian dollar and the U.S. dollar and the Australian dollar and mature at specified monthly settlement dates through June 2018. At inception, the Company designated the foreign currency forward contracts as cash flow hedges. Upon purchase of certain inventories, the Company de-designates the foreign currency forward contract. On October 4, 2016, the Company entered into a cross currency swap arrangement to hedge changes in foreign currency exchange rates. As of September 30, 2017 , the notional amount of the cross currency swap was approximately $117.0 million . The Company uses the cross currency swap to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to a non-U.S. denominated intercompany loan of €110.0 million . The cross currency swap hedges currency exposure between the Euro and the U.S. dollar and matures on January 3, 2019. The Company makes quarterly principal payments of €1.4 million , plus interest at a fixed rate of 5.4% per annum, in exchange for $1.5 million , plus interest at a fixed rate of 7.2% per annum. At inception, the Company designated the cross currency swap as a cash flow hedge. Changes in the currency rate result in reclassification of amounts from accumulated other comprehensive income to earnings to offset the re-measurement gain or loss on the non-U.S. denominated intercompany loan. Additionally, during the third quarter of 2017, the Company’s Australian subsidiary entered into a cross currency swap arrangement to hedge changes in foreign currency exchange rates. As of September 30, 2017 , the notional amount of the cross currency was approximately $6.6 million . The Australian subsidiary uses the cross currency swap to mitigate the risk associated with fluctuations in currency rates related to a non-functional currency intercompany loan of NZ $10.0 million . The floating-to-floating cross currency swap hedges currency exposure between the New Zealand dollar and the Australian dollar and matures on June 30, 2020. The Australian subsidiary makes quarterly principal payments of NZ $0.8 million , plus interest at the 3-month Bank Bill Benchmark Rate ("BKBM") in New Zealand plus a margin of .31% per annum, in exchange for A $0.8 million , plus interest at the 3-month BBSY in Australia per annum. At inception, the cross currency swap was not designated as a hedging instrument.

Segment Reporting [Abstract]
Segment Information	Segment Information Horizon groups its operating segments into reportable segments by the region in which sales and manufacturing efforts are focused. Each operating segment has discrete financial information evaluated regularly by the Company’s chief operating decision maker in determining resource allocation and assessing performance. In the fourth quarter of 2016, as a result of the Westfalia Group acquisition, the Company realigned its executive management structure which changed the information used by our chief operating decision maker to assess performance and allocate resources. As a result, the Company reports the results of its business in three reportable segments: Horizon Americas, Horizon Europe‑Africa, and Horizon Asia‑Pacific. The Company’s Brazilian operations, which has previously been included in the Horizon International reportable segment, is now managed as part of its former Horizon North America segment, which has been renamed Horizon Americas.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Awards	Equity Awards Description of the Plan Horizon employees and non-employee directors participate in the Horizon Global Corporation 2015 Equity and Incentive Compensation Plan (as amended and restated, the “Horizon 2015 Plan”). The Horizon 2015 Plan authorizes the Compensation Committee of the Horizon Board of Directors to grant stock options (including “incentive stock options” as defined in Section 422 of the U.S. Internal Revenue Code), restricted shares, restricted stock units, performance shares, performance units, cash incentive awards, and certain other awards based on or related to our common stock to Horizon employees and non-employee directors. No more than 2.0 million Horizon common shares may be delivered under the Horizon 2015 Plan. Stock Options The following table summarizes Horizon stock option activity from December 31, 2016 to September 30, 2017 : Number of Weighted Average Exercise Price Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Outstanding at December 31, 2016 347,585 $ 10.37 Granted — — Exercised (3,638 ) 10.40 Canceled, forfeited — — Expired — — Outstanding at September 30, 2017 343,947 $ 10.37 8.1 $ 2,499,061 As of September 30, 2017 , there was $0.2 million in unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 0.5 years. The Company recognized approximately $0.1 million and $0.3 million of stock-based compensation expense related to stock options during the three and nine months ended September 30, 2017 , respectively, and approximately $0.2 million and $0.6 million during the three and nine months ended September 30, 2016 , respectively. Stock-based compensation expense is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of income. Restricted Shares In the first nine months of 2017, the Company granted an aggregate of 185,423 restricted stock units and performance stock units to certain key employees and non-employee directors. The total grants consisted of: (i) 22,449 time-based restricted stock units that vest ratably on (1) March 1, 2018, (2) March 1, 2019 and (3) March 1, 2020; (ii) 50,416 time-based restricted stock units that vest ratably on (1) March 1, 2018, (2) March 1, 2019, (3) March 1, 2020 and (4) March 1, 2021; (iii) 72,865 market-based performance stock units that vest on March 1, 2020; (iv) 33,426 time-based restricted stock units that vest on July 1, 2018, and (v) 6,267 time-based restricted stock units that vest on July 1, 2019. The performance criteria for the market-based performance stock units is based on the Company’s total shareholder return (“TSR”) relative to the TSR of the common stock of a pre-defined industry peer group, measured over a period beginning January 1, 2017 and ending December 31, 2019. TSR is calculated as the Company’s average closing stock price for the 20-trading days at the end of the performance period plus Company dividends, divided by the Company’s average closing stock price for the 20-trading days prior to the start of the performance period. Depending on the performance achieved, the amount of shares earned can vary from 0% of the target award to a maximum of 200% of the target award. The Company estimated the grant-date fair value of the awards subject to a market condition using a Monte Carlo simulation model, using the following weighted-average assumptions: risk-free interest rate of 1.52% and annualized volatility of 38.5% . Due to the lack of adequate stock price history of Horizon common stock, the expected volatility is based on the historical volatility of the common stock of the peer group. The grant date fair value of the performance stock units was $18.41 . The grant date fair value of r estricted shares is expensed over the vesting period. Restricted share fair values are based on the closing trading price of the Company’s common stock on the date of grant. Changes in the number of restricted shares outstanding for the period ended September 30, 2017 were as follows: Number of Restricted Shares Weighted Average Grant Date Fair Value Outstanding at December 31, 2016 557,563 $ 11.89 Granted 185,423 17.49 Vested (153,086 ) 12.52 Canceled, forfeited — — Outstanding at September 30, 2017 589,900 $ 13.50 As of September 30, 2017 , there was $4.0 million in unrecognized compensation costs related to unvested restricted shares that is expected to be recognized over a weighted-average period of 0.9 year. The Company recognized approximately $0.9 million and $2.5 million of stock-based compensation expense related to restricted shares during the three and nine months ended September 30, 2017 , respectively, and approximately $0.8 million and $2.2 million during the three and nine months ended September 30, 2016 , respectively. Stock-based compensation expense is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of income.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share is computed using net income attributable to Horizon Global and the number of weighted average shares outstanding. On February 1, 2017, the Company completed an underwritten public offering of 4.6 million shares of common stock, which includes the exercise in full by the underwriters of their option to purchase 0.6 million shares of common stock, at a public offering price of $18.50 per share (the “Common Stock Offering”). Proceeds from the Common Stock Offering were approximately $79.9 million , net of underwriting discounts, commissions, and offering-related transaction costs. Diluted earnings per share is computed using net income attributable to Horizon Global and the number of weighted average shares outstanding, adjusted to give effect to the assumed exercise of outstanding stock options and warrants, vesting of restricted shares outstanding, and conversion of the Convertible Notes. The following table sets forth the reconciliation of the numerator and the denominator of basic earnings per share attributable to Horizon Global and diluted earnings per share attributable to Horizon Global for the three and nine months ended September 30, 2017 and 2016 : Three months ended Nine months ended 2017 2016 2017 2016 (dollars in thousands, except for per share amounts) Numerator: Net income attributable to Horizon Global $ 6,890 $ 370 $ 17,290 $ 9,890 Denominator: Weighted average shares outstanding, basic 24,948,410 18,174,509 24,728,643 18,144,998 Dilutive effect of stock-based awards 430,842 344,568 426,157 188,228 Weighted average shares outstanding, diluted 25,379,252 18,519,077 25,154,800 18,333,226 Basic earnings per share attributable to Horizon Global $ 0.28 $ 0.02 $ 0.70 $ 0.55 Diluted earnings per share attributable to Horizon Global $ 0.27 $ 0.02 $ 0.69 $ 0.54 The effect of certain common stock equivalents were excluded from the computation of weighted average diluted shares outstanding for the three and nine months ended September 30, 2017 and 2016 , as inclusion would have resulted in anti-dilution. A summary of these anti-dilutive common stock equivalents is provided in the table below: Three months ended Nine months ended 2017 2016 2017 2016 Number of options — — — 268,331 Exercise price of options — — — $10.08 - $11.02 Restricted stock units — — 57,118 53,546 Convertible Notes 5,005,000 — 4,418,333 — Warrants 5,005,000 — 4,418,333 — For purposes of determining diluted earnings per share, the Company has elected a policy to assume that the principal portion of the Convertible Notes, as described in Note 7 , “ Long-term Debt ,” is settled in cash and the conversion premium is settled in shares. Therefore, the Company has adopted a policy of calculating the diluted earnings per share effect of the Convertible Notes using the treasury stock method. As a result, the dilutive effect of the Convertible Notes is limited to the conversion premium, which is reflected in the calculation of diluted earnings per share as if it were a freestanding written call option on the Company’s shares. Using the treasury stock method, the Warrants issued in connection with the issuance of the Convertible Notes are considered to be dilutive when they are in the money relative to the Company’s average common stock price during the period. The Convertible Note Hedges purchased in connection with the issuance of the Convertible Notes are always considered to be anti-dilutive and therefore do not impact the Company’s calculation of diluted earnings per share.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim reporting period, the Company makes an estimate of the annual effective income tax rate. Tax items included in the annual effective income tax rate are pro-rated for the full year and tax items discrete to a specific quarter are included in the effective income tax rate for that quarter. The estimate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods. The Company has experienced pre-tax losses in the U.S. In light of the losses, the Company evaluates the realizability of its deferred tax assets on a quarterly basis. In completing this evaluation, the Company considers all available evidence in order to determine whether, based on the weight of the evidence a valuation allowance is necessary. As of September 30, 2017 , we believe that it is more likely than not that the U.S. deferred tax assets will be realized. If the U.S. business continues to experience losses through 2017, management may determine a valuation allowance against the U.S. deferred tax assets is necessary, which would result in significant tax expense in the period recognized, as well as subsequent periods. The effective income tax rate was (1.9)% and (25.7)% for the three and nine months ended September 30, 2017 , respectively. For the three and nine months ended September 30, 2016 , the effective income tax rates were 75.8% and 8.3% , respectively. The lower effective income tax rate in the three months ended September 30, 2017 is driven by a higher portion of income earned in jurisdictions with lower statutory rates and the recognition of additional tax credits recognized in the U.S. The lower effective income tax rate in the nine months ended September 30, 2017 is driven by the recognition of the income tax benefits associated with stock awards issued, the release of certain unrecognized tax positions, and the recognition of additional tax credits in the U.S. During the nine months ended September 30, 2017 and 2016 , cash paid for domestic taxes was approximately $1.9 million and $1.9 million , respectively. During the nine months ended September 30, 2017 and 2016 , the Company paid cash for foreign taxes of $4.2 million and $2.2 million , respectively.
