Nilight LED Light Bar Wiring Harness Kit 2PCS 16AWG – Dual Leads, Relay & Blade Fuse with Illuminated Switch

Nilight's 2PCS 16AWG LED light bar wiring harness kit is a ready-to-install 12V relay, blade-fuse and illuminated rocker-switch solution for powering two LED fixtures safely and reliably.

This compact wiring kit bundles the essential electrical components to add an on/off switch and fused relay control to off-road lights, work lights, or auxiliary LED bars. Built around 16AWG wiring and a relay protected by a blade fuse, the harness is designed to simplify installation, prevent overloads, and give you cleaner, safer wiring for vehicles, boats, or other 12V systems.

How does this harness protect my lights and vehicle wiring?

The harness centers around a power relay and inline blade fuse that isolates the switch circuit from the high-current LED load. If a short or overcurrent happens, the blade fuse opens the circuit to prevent damage. This layered protection keeps both the lights and the vehicle’s wiring safer under heavy use.

• Power relay separates switch circuit from high-current draw.
• Blade fuse interrupts current during shorts or overloads.
• 16AWG wire balances flexibility and current capacity for typical LED bars.
• Robust connectors reduce resistance and heat at load points.

What makes installation straightforward for DIYers?

The harness arrives pre-assembled with an illuminated 3-pin rocker switch, relay, fused holder, and two output leads so you can hook up two fixtures without splicing multiple runs. Clear connectors and a step-by-step instruction sheet minimize guesswork and speed up the job for common vehicle mounting locations.

• Plug-and-play terminals for quick connections.
• Illuminated rocker switch shows when the circuit is active.
• Two output leads let you power dual lights up to the harness rating.
• Included instructions help guide routing and fuse placement.

Can I use this harness with my specific lighting setup?

Yes — the harness is made for any 12V system and supports paired LED fixtures with a combined draw under the kit’s rated capacity (confirm total wattage before use). Its universal terminals work with automotive, marine, and utility LED bars when wired correctly.

• Compatible with automobiles, boats and 12V devices.
• Two leads accommodate dual fixtures up to the harness limit.
• Check combined wattage to ensure you stay within safe current levels.
• Relay-based switching suits heavy LED loads better than direct-switch wiring.

How durable and long-lasting is the Nilight harness?

Components are chosen for everyday off-road and marine use: a sealed relay, a durable blade fuse holder, and a switch rated for many cycles. Nilight supports the kit with a 2-year warranty, reflecting confidence in part longevity under normal installation and use.

• Switch tested for 5,000 presses for reliable operation.
• Blade fuse and relay protect against electrical faults.
• 16AWG wiring resists abrasion while remaining flexible for routing.
• 2-year warranty included for added peace of mind.

Who is this for? Installers, DIY vehicle owners, and fleet operators who want a safer, neater way to add or control two LED lights from a single switch will find this Nilight kit practical. It’s particularly useful for off-road enthusiasts, tradespeople fitting work lights, and anyone upgrading auxiliary lighting on cars, trucks, ATVs, or boats who prefers a fused, relay-driven approach over ad-hoc wiring.
