Instead of plugging into preexisting sockets, this taillight converter splices directly into your vehicle's taillight wiring to create a simple 2-wire trailer circuit. It arrives ready to install with blunt-cut, color-coded leads and is built for interior mounting on vehicles that use conventional incandescent lighting.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the CURT 58240 convert my vehicle's wiring for towing?\u003c\/h3\u003e\n\u003cp\u003eThis unit takes the three separate vehicle tail light signals and merges them into a two-wire trailer output so a trailer's lights operate correctly with your vehicle's incandescent system.

Because it sits inside the vehicle and avoids exposure to road conditions, it provides stable electrical connections when installed correctly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eColor-coded wires simplify correct splicing and reduce installation errors\u003c\/li\u003e\n  \u003cli\u003eInterior mounting prolongs component life by avoiding moisture and road salt\u003c\/li\u003e\n  \u003cli\u003eRated for signal and taillight circuits (2.1 amps for signal, 5.0 amps for taillight)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The CURT 58240 is aimed at DIYers, RV owners who dinghy tow, and anyone needing a simple splice-in trailer lighting solution for vehicles with incandescent taillights. Choose this converter if you want a ready-to-install, interior-mounted unit that converts a 3-wire system to a 2-wire trailer output and you do not have or cannot source a vehicle-specific custom harness. Avoid it if your vehicle uses LED lighting or if you require an externally mounted, powered converter for higher-current applications.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the CURT 58240 with LED tail lights?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The CURT 58240 is not compatible with LED lighting and is intended only for incandescent systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this converter require a battery or heavy-duty flasher?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. It is a non-powered unit and installs without a direct battery connection or special flasher.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"CURT","offers":[{"title":"Default Title","offer_id":55162869580119,"sku":"B001EP0GI6","price":31.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/curt-58240-front-module.jpg?v=1790339350","url":"https:\/\/britishgarage.co.uk\/products\/curt-58240-3-to-2-wire-tail-light-converter-interior-mount-for-incandescent-systems-non-powered-splice-in","provider":"British Garage","version":"1.0","type":"link"}
