Designed for vehicles and marine craft that use 12V systems, the kit simplifies wiring while improving safety and switch accessibility compared with ad hoc splices. The harness comes assembled with ten feet of cable so you can route power from the battery to bumper-mounted or roof-mounted lights without splicing multiple cable runs.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the relay and fuse protect my lights and vehicle?\u003c\/h3\u003e\n\u003cp\u003eThe included electromagnetic relay prevents high current from flowing through the switch, keeping the switch contacts cool and extending component life. The inline blade fuse is the first line of defense against short circuits or sudden overcurrent, protecting wiring and lights from damage. Together they make the kit much safer than direct-switch wiring.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSealed power relay handles switching duty for high-current LED loads.\u003c\/li\u003e\n  \u003cli\u003eInline blade fuse positioned close to the battery minimizes wiring exposure.\u003c\/li\u003e\n  \u003cli\u003e12AWG leads reduce voltage drop for longer runs and high-draw fixtures.\u003c\/li\u003e\n  \u003cli\u003ePre-assembled connections lower installation errors and heat risks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I run two lights from this harness and what are the limits?\u003c\/h3\u003e\n\u003cp\u003eThe harness supplies two output leads specifically to power dual fixtures while keeping connections tidy and stable. It supports combined loads up to roughly 450W for 12V systems—suitable for most LED light bars and pairs of work lights—so verify the wattage of your lights before installation. Using the two leads prevents overloading a single output and makes mounting two separate fixtures simple.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo output connectors: wire two LED fixtures without extra splices.\u003c\/li\u003e\n  \u003cli\u003eRated for combined loads up to about 450W on 12V systems.\u003c\/li\u003e\n  \u003cli\u003e12AWG wiring reduces heat and voltage drop for longer cable runs.\u003c\/li\u003e\n  \u003cli\u003ePlug-and-play connectors speed up installation on jeeps, ATVs, or trucks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes the illuminated rocker switch useful on the trail or at night?\u003c\/h3\u003e\n\u003cp\u003eThe three-pin on\/off rocker switch has a red indicator that lights when powered, making it easy to confirm the circuit is active even in the dark. The switch is tested for durability (thousands of actuations) and is user-friendly to operate with gloved hands or while driving on rough terrain. Its 3-pin wiring supports backlighting while retaining a clean installation footprint in dash panels or mounting blocks.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRed backlight shows switch status at a glance in low light.\u003c\/li\u003e\n  \u003cli\u003e3-pin design keeps backlight and power separate for reliable switching.\u003c\/li\u003e\n  \u003cli\u003eDurability-tested for repeated use in harsh conditions.\u003c\/li\u003e\n  \u003cli\u003eCompact shape fits common dash cutouts and mounting panels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Nilight 10-foot, 12AWG dual-lead wiring harness is aimed at DIY installers and professional mechanics fitting auxiliary LED lighting on 12V vehicles—jeeps, trucks, ATVs, UTVs, motorcycles, boats, and trailers. It's ideal for anyone who wants a safer, cleaner, and faster wiring solution than loose wires and inline switches: it reduces installation time, offers surge protection, and supports two fixtures without complicated splicing. If you need longer cable runs, higher wattage capacity, or custom connectors, review your lights' specifications and consider upgrading gauge or relay components accordingly before purchase.\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: Will this harness work with a single high-power LED light?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, but ensure the single light's wattage does not exceed the harness's combined 450W 12V rating; otherwise use a heavier-duty harness.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the kit include the battery terminal connector?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The kit includes ten feet of harness and connectors; basic battery terminal hardware may be required depending on your vehicle.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Nilight","offers":[{"title":"Default Title","offer_id":48087046324382,"sku":"B0948YVR9C","price":33.34,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/nilight-harness-front-packaging.jpg?v=1785915112","url":"https:\/\/northtrailauto.ca\/products\/nilight-led-light-bar-wiring-harness-kit","provider":"North Trail Auto","version":"1.0","type":"link"}
