Nilight 10011W Wiring Harness 16AWG 2-Lead — 5‑Pin Rocker Switch, Relay & Fuse for 12V LED Light Bars

The Nilight 10011W wiring harness kit is a complete 12V installation bundle with two output leads, a power relay, inline blade fuse and a 5‑pin LED rocker switch for safely powering up to 180W of LED light bars.

This harness streamlines adding one or two LED light fixtures to vehicles and marine craft without splicing into the factory wiring. Built on 16AWG cabling, the assembly includes factory‑style connectors, a sealed relay and fuse holder plus two soft white LEDs in the switch so you can locate it at night. The kit is engineered for straightforward mounting and broad compatibility with jeeps, trucks, ATVs, UTVs, motorcycles, boats and trailers using a standard 12V battery.

How does this harness simplify installing LED light bars?

Pre‑terminated leads and labeled connectors remove most of the guesswork when wiring aftermarket lights. The included relay handles the high current draw so the switch and vehicle wiring only carry control current, reducing heat and resistance risks.

• Two output leads let you power dual fixtures from one battery source.
• 12 feet of cable provides flexible routing options through engine bays or behind bumpers.
• Plug‑and‑play connectors reduce the need for crimping or soldering.

What safety features are included to protect my vehicle's electrical system?

Nilight built sensible protection into the kit so the most common failure modes are guarded against. A dedicated power relay and an inline blade fuse act as primary defenses against overcurrent and short circuits, while the switch is rated for repeated cycling.

• Inline blade fuse positioned close to the battery input for immediate protection.
• Sealed power relay handles higher loads and minimizes voltage drop to the lights.
• 16AWG wiring balances flexibility with sufficient current capacity for typical 12V light bars.

Will the illuminated rocker switch help during night driving or offshore use?

Yes — the 5‑pin rocker switch has two built‑in LEDs that emit a soft glow to make the control easy to find in low light. The illumination also signals switch status at a glance, which is useful when operating lights from within the cabin or helm.

• Dual LED indicators ensure visibility in dark cabins or cockpits.
• Compact rocker shape fits standard dash cutouts or simple surface mounts.
• Five pins provide separate power, ground and relay trigger terminals for neat wiring.

How adaptable is this harness across different vehicle types?

The kit was designed for broad 12V compatibility, so it pairs easily with many aftermarket LED light bars and vehicle platforms. Because it provides two outputs and a generous cable length, you can run lights on the front bumper, roof rack, or tow package without customizing new cables.

• Suitable for jeeps, trucks, ATVs, UTVs, motorcycles, boats and trailers.
• Two output connectors support dual light setups under 180W combined.
• Instructions included to simplify routing and mounting decisions.

Who is this for? The Nilight 10011W harness is aimed at DIY installers, off‑road enthusiasts and marine owners who want a reliable, ready‑to‑fit wiring solution for one or two 12V LED light bars. It’s ideal if you value clear switch visibility at night, want in‑line protection for your battery circuit, and prefer avoiding complex custom wiring. The kit includes the wiring harness, a 5‑pin LED rocker switch and straightforward instructions, plus Nilight’s two‑year warranty for peace of mind.
