Nilight 12V Off-Road LED Light Bar Wiring Harness Kit - 5‑Pin Illuminated Rocker Switch, 180W Protection

Nilight's 12V Off Road LED Light Bar Wiring Harness Kit is a complete plug-and-play wiring solution that powers up to 180W of LED lighting using a heavy-duty relay, inline fuse, and a 5‑pin illuminated rocker switch.

This wiring harness is designed to simplify installation and protect your LED light bars on cars, trucks, ATVs, UTVs, boats and trailers. It combines rugged 16 AWG stranded wiring with a nylon jacket, a power relay to handle high loads, and a replaceable inline blade fuse to guard against overcurrent. The included Nilight 5‑pin SPST rocker switch features built‑in LEDs for low‑light visibility and two output leads for driving dual lights or splitting power to multiple fixtures.

How does the harness protect my lights and vehicle electrical system?

The kit uses a dedicated power relay and an inline blade fuse to reduce the risk of overcurrent or wiring damage. Relay-based switching keeps high current away from the dashboard switch, while the fuse acts as the primary overcurrent safeguard. Together they extend the life of both your lights and vehicle wiring.

• 16 AWG stranded wire rated for up to 180W total load
• Power relay handles high current switching safely
• Inline blade fuse protects against short circuits and overloads
• Nylon jacket resists abrasion, heat and environment exposure

What makes the Nilight 5‑pin rocker switch user-friendly?

The included 5‑pin SPST rocker switch is straightforward to install and operate. Two small internal LEDs softly illuminate the switch so you can find it in darkness without causing glare. The SPST design provides a simple on/off control while the five pins allow easy wiring into the relay and accessory circuits.

• Illuminated switch with soft LEDs for nighttime visibility
• SPST (single pole single throw) design for simple on/off control
• Five‑pin layout simplifies wiring to relay and power source
• Compact form factor fits standard switch panels or custom mounts

Can this harness run two light bars or multiple fixtures?

Yes — the kit provides two output leads so you can power dual fixtures or create separate feeds for multiple lights, as long as the combined load stays below 180W. The dual‑lead setup helps balance connections and reduces reliance on splitters that can introduce resistance or failure points.

• Two sets of light output connectors for dual fixtures or staged lighting
• Total supported load up to 180W at 12V
• Stable connections minimize voltage drop across outputs
• Works with most 12V LED light bars, spot/flood combos and auxiliary lights

Where and how can I use this wiring harness?

The harness is built for a wide range of 12V vehicles and marine craft, making it a flexible choice for off‑road, work, and recreational lighting projects. Its durable nylon outer jacket and quality connectors allow installation in engine bays, underdash areas, bumper mounts, roll cages or on trailers with reduced risk of chafing or heat damage.

• Compatible with automobiles, trucks, campers, ATVs, UTVs and motorcycles
• Suitable for boats, yachts and marine auxiliary lights (12V systems)
• Designed for in‑vehicle mounts, bumper or roof installations
• Durable materials for outdoor and high‑temperature environments

Who is this for? The Nilight Off Road LED Light Bar Wiring Harness Kit is aimed at DIY installers, professional mechanics and outdoor enthusiasts who need a reliable, easy‑to‑install wiring solution for 12V LED lighting. If you want a safer swap than ad‑hoc wiring, illuminated switch control for night use, and the ability to run two fixtures while protecting circuits with a relay and fuse, this kit delivers a straightforward, durable option.
