Nilight LED Light Bar Wiring Harness Kit NI-WA07 — 12V Dual Output, 5‑Pin Waterproof Rocker, 12ft Leads

Nilight 10013W NI-WA07 is a ready-to-install 12V wiring harness kit with a 5-pin waterproof rocker switch, relay, inline fuse and dual 12-foot leads for powering up to two LED light fixtures safely.

This complete wiring kit supplies a clean, protected electrical path for off-road and marine LED light bars. Built with a heavy-duty relay, inline blade fuse and a waterproof 5-pin rocker switch that lights for night visibility, the harness simplifies wiring two light fixtures while helping prevent overloads and short circuits. The plug-and-play layout reduces installation time and keeps wiring tidy under hoods, behind bumpers or in cabins.

How does this harness protect my lights and vehicle wiring?

The kit includes an automotive-grade power relay and an inline blade fuse that act as first-line safety devices to cut power under fault conditions. That arrangement keeps high current off your vehicle’s factory switch circuits and confines any electrical problems to the harness fuse.

• Inline blade fuse for quick replacement and overcurrent protection
• Power relay routes high current directly from the battery to the lights
• Durable connectors reduce risk of loose or corroded joints
• Waterproof switch housing shields controls from moisture

Will this work for two light bars and how long are the leads?

The wiring harness has two separate light-output connectors and two 12-foot leads (extendable), enabling connection of dual LED fixtures whose combined draw is under 180W. The twin outputs let you run paired light bars or a combination of flood and spot units without extra adapters.

• Two sets of output connectors for dual fixtures
• Each lead: 12 feet, extendable for versatile mounting positions
• Rated to support combined loads below 180W
• Quick-disconnect plug design speeds installation

Is the switch easy to find at night and weather-resistant?

Yes—this kit supplies a backlit 5-pin LED rocker switch so you can see the control in low light, and the switch assembly is designed to resist water ingress. The illuminated switch simplifies nighttime operation while the waterproof construction makes it suitable for exposed dash or external mounts.

• Built-in LED in the rocker switch for nighttime visibility
• Waterproof switch housing for damp environments
• 5-pin design supports accessories like rocker illumination and power feed
• Compact footprint fits most dash openings or panels

Who is this for? Off-roaders, boat owners, and DIY vehicle modifiers who need a safe, tidy and reliable way to power two 12V LED light fixtures will benefit from the Nilight 10013W NI-WA07 harness. It’s suited to jeeps, ATVs, UTVs, trucks, motorcycles, trailers and small boats when you want a plug-and-play wiring solution that adds protection, visible controls and room to route cables neatly. The kit includes the harness, the illuminated 5-pin rocker switch and an instruction sheet to help with installation.
