Nilight LED Light Bar Wiring Harness Kit 2PCS 16AWG 12V — 180W Capacity, Relay & Inline Fuse with Illuminated Switch

Nilight's 2PCS 16AWG LED Light Bar Wiring Harness Kit is a ready-to-install 12V wiring solution that includes a fused relay, illuminated on/off rocker switch, and two output leads for powering up to 180W of off-road or work lights.

This harness is built to simplify adding LED light bars to vehicles, boats, ATVs and other 12V systems. It combines a heavy-duty 16AWG power cable with a blade fuse, a power relay to protect circuitry, and a three-pin illuminated rocker switch that has been tested for long-term use. The kit gives a neat, plug-and-play alternative to ad-hoc wiring, reducing installation time and improving safety compared with directly wiring to a battery without protection.

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

The harness includes a dedicated power relay and an inline blade fuse that prevent overcurrent and isolate the light circuit from sensitive vehicle electronics. If a short or overload occurs, the fuse interrupts current flow and the relay keeps the circuit controlled during normal operation. This lowers the risk of wiring damage and reduces electrical interference compared with unprotected setups.

• Inline blade fuse provides fast overcurrent protection
• Power relay switches high current through a controlled circuit
• 16AWG cable balances flexibility with sufficient current capacity
• Pre-wired connectors limit user wiring errors

Can I run two LED lights from this kit and what wattage is supported?

Yes — the harness has two output leads so you can connect dual lighting fixtures while keeping each run stable. The combined load supported is up to approximately 180W at 12V, which covers most single light bars or a pair of lower-powered work lights. Always check the combined wattage of your LED fixtures before connecting.

• Two output leads for dual fixtures or dual beam setups
• Rated to support up to ~180W total at 12V
• Separate connectors reduce shared-connector stress
• Clear wiring diagram included for correct hookups

How easy is installation and what tools do I need?

This harness is designed for quick installation with basic hand tools: a wrench, wire cutters/strippers and a screwdriver. It arrives with pre-crimped connectors and an instruction sheet, so most users can complete the job in under an hour depending on mounting and routing. The illuminated rocker switch mounts in a 3-pin hole and the battery leads attach directly to the 12V source.

• Pre-terminated connectors reduce soldering or crimping work
• Includes instructions to speed installation
• Mountable illuminated rocker switch for dash or panel use
• Simple battery and ground connections for a secure setup

What durability and reliability features does the kit offer?

The wiring harness uses automotive-grade components chosen for vibration resistance and repeated switching. The illuminated rocker switch has been tested for thousands of actuations, while the blade fuse and relay are standard automotive parts that are easy to replace if needed. Nilight backs the product with a two-year warranty for peace of mind under normal use.

• Military-style relay and blade fuse for serviceability
• Switch rated for 5,000+ press cycles in tests
• 16AWG wire for improved flex and heat resistance
• Two-year warranty from Nilight for covered defects

Who is this for: The Nilight 16AWG dual-lead harness is aimed at DIYers, off-road enthusiasts, mechanics and fleet technicians who need a reliable, protected wiring solution for LED light bars and work lights on 12V platforms. It’s especially useful when you want a tidy, safe installation with an illuminated dash switch and the ability to run two fixtures without fabricating a custom loom.
