Nilight 16 AWG Nylon LED Light Bar Wiring Harness Kit — 2-Lead, Relay & Illuminated Switch, 180W

Nilight's 16 AWG Nylon LED Light Bar Wiring Harness Kit is a complete, heavy-duty 2-lead wiring solution that includes a relay, inline fuse, and illuminated rocker switch for safely powering up to 180W of 12V lighting.

When adding LED light bars or auxiliary lights to a vehicle, a purpose-built harness reduces installation time and protects both your electrical system and your lamps. This Nilight kit combines 16 AWG stranded wiring, a power relay, an inline blade fuse, and a 5-pin illuminated rocker switch in a flexible nylon jacket so you can install dual light outputs with confidence across cars, trucks, ATVs, boats, and RVs.

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

The kit routes power through a dedicated relay and an inline blade fuse, preventing overloads and isolating the accessory circuit from your factory wiring. Using a relay means the switch carries minimal current and reduces heat and wear on existing wiring harnesses.

• 16 AWG stranded wiring for reliable current capacity
• Inline blade fuse provides first-line overcurrent protection
• Power relay isolates accessory draw from stock circuits
• Nylon jacket resists abrasion and high temperatures

What components are included and how do they simplify installation?

The kit arrives ready to integrate: a pre-wired relay, fuse holder with fuse, an illuminated 5-pin SPST rocker switch, and two output leads for dual fixtures. Pre-crimped connectors and labeled leads minimize guesswork so you can mount the switch and tie into a 12V battery quickly.

• Illuminated 5-pin rocker switch for easy on/off control
• Two separate light output leads for dual fixtures under 180W combined
• Pre-terminated connectors for fast, secure hookups
• Clear labeling and a compact relay/fuse assembly for tidy routing

Will this kit work with my specific lights and vehicle type?

This harness is designed for 12V systems and supports lighting loads up to 180W total, which covers many LED light bars and auxiliary lamps commonly used on road and off-road vehicles. The universal connectors and flexible nylon jacket make it usable on cars, trucks, ATVs, motorcycles, boats, and trailers.

• Compatible with most 12V LED light bars and spot/flood lamps
• Two leads let you run two fixtures or a dual-light assembly
• Works on automotive, marine, and powersports 12V systems
• Use within the 180W combined load limit for safe operation

How durable and serviceable is the harness over time?

The wiring is sleeved in a high-quality nylon jacket that improves abrasion resistance and heat tolerance compared with bare wires, while the relay and fuse are mounted for easy access and replacement. If any component requires replacement, standard inline fuses and common relay sizes keep maintenance straightforward.

• Nylon jacket offers flexibility and high-temperature resistance
• Replaceable inline blade fuse for quick servicing in the field
• Standard relay footprint simplifies part swaps if needed
• Stranded 16 AWG conductors balance flexibility with current capacity

Who is this for? Installers, DIY vehicle owners, and mechanics who need a reliable, ready-made wiring solution for LED light bars and auxiliary lighting will value this Nilight kit. It suits anyone fitting dual lights on passenger vehicles, trucks, off-road rigs, trailers, RVs, or marine craft who wants a safer, cleaner electrical installation without fabricating custom wiring or hunting individual components.
