Nilight LED Light Bar Wiring Harness 2-Pack 16AWG 12V — Dual-Output with Relay, Blade Fuse & Illuminated Switch

Nilight's 2PCS 16AWG LED light bar wiring harness kit is a ready-to-install 12V power kit with dual outputs, relay protection, illuminated on/off switch and blade fuse designed for powering two off-road or work lights up to 180W total.

This harness simplifies adding LED light bars to cars, trucks, boats, ATVs and other 12V systems. It bundles a heavy-duty relay, a replaceable blade fuse and a durable 3-pin illuminated rocker switch on 16AWG wiring so you get a reliable, protected circuit without splicing together multiple parts. The kit includes two output leads so you can run a pair of fixtures from one switched source, and its universal connectors suit most aftermarket LEDs.

How does this harness protect my vehicle's electrical system?

The kit places a powered relay between the switch and the light load so the vehicle's factory switch and wiring aren't carrying full current. A blade fuse sits inline with the relay output to interrupt power if an overcurrent or short occurs, minimizing risk to wiring and components.

• Power relay routes high current directly from battery to lights
• Replaceable blade fuse protects against shorts and overloads
• 16AWG wiring balances flexibility and current capacity for typical LED loads

What does the illuminated switch do and how durable is it?

The included 3-pin rocker switch offers a clear red indicator light when the circuit is on, so you can spot activation at a glance. It's been engineered for repeated use and tested for long switch cycles to ensure consistent performance in daily driving or worksite conditions.

• Red illuminated rocker shows when lights are powered
• 3-pin design for simple on/off control and relay trigger
• Durability tested for thousands of actuations for reliable operation

Can I run two light fixtures from this single harness?

Yes — this kit provides two output leads so two LED bars or lights can be powered and switched together from one harness. Total combined load should remain within the kit’s rated capacity (under 180W) to maintain safe operation and fuse protection.

• Two separate output connectors for dual fixtures
• Recommended combined power below 180W for stable performance
• Common switched source simplifies wiring and installation

How easy is installation and which vehicles are compatible?

Installation is straightforward for anyone comfortable with basic 12V wiring: connect the fused relay to the battery, mount the switch in a dash panel hole, and attach the two outputs to your light bars. The harness is a universal 12V accessory compatible with most cars, trucks, ATVs and boats.

• Plugs and wires pre-assembled for fast installation
• Works with any 12V system on vehicles and marine applications
• Includes simple instructions to guide basic wiring steps

Who is this for? Installers, DIY vehicle owners and fleet technicians who need a compact, protected way to control two LED lights from one switch will find this kit useful. It's ideal for off-roaders adding auxiliary lighting, tradespeople outfitting service vehicles, and boat owners needing a tidy, reliable 12V control solution. If you want to avoid custom harness fabrication while keeping circuit protection and an illuminated dash switch, this Nilight kit provides a practical, ready-to-fit option.
