Installing auxiliary lights on your vehicle shouldn’t mean wrestling with complicated wiring or risking electrical issues. This Nilight LED light bar wiring harness delivers a complete plug-and-play solution with dual-circuit control, letting you manage front and rear lighting independently through a single, professional-grade switch panel.

The harness uses heavy-duty 16AWG stranded wire rated for up to 360W total load—180W per circuit. That’s enough power to run multiple LED light bars, work lights, or fog lights without breaking a sweat. Built-in power relays and inline blade fuses protect your electrical system from overcurrent and short circuits, giving you reliable operation even in demanding conditions.

Who Is This For?

This kit works for anyone adding auxiliary lighting to a 12V vehicle. Off-road enthusiasts can wire front-facing spotlights and rear-facing work lights with independent control. RV and camper owners get separate switches for exterior camp lighting and underbody illumination. Truck owners can control bed lights separately from bumper-mounted LED bars. The four-lead design means you’re not limited to a single light per switch—run two lights per circuit and control them together.

The laser-etched rocker switches feature blue indicator lights and have been tested through 5,000 press cycles. The pattern won’t fade, and the switches mount cleanly in your dash or console. Installation is straightforward with included blade fuses and spade connectors—no electrical engineering degree required.

Bottom Line

If you need a reliable way to add and control multiple auxiliary lights on your truck, Jeep, ATV, UTV, boat, or RV, this harness eliminates the guesswork. The dual-circuit design with independent switching gives you flexibility, while the heavy-duty components and built-in protection ensure your lighting setup works when you need it. Nilight backs it with a 2-year warranty, and the kit includes everything you need to get wired up properly the first time.
