Nilight Dual-Color Light Bar Wiring Harness for Amber/White LEDs — 16AWG Dual-Relay Kit with Push-Button Switch

Nilight 10031W is a ready-to-install wiring harness kit that lets you control amber and white channels of a dual-color 12V light bar with two relays, two 15A inline fuses and a user-friendly push-button switch.

This harness is built to simplify wiring for off-road lighting setups that use split amber/white beams. It includes heavy-duty 16AWG wiring, two relay circuits for reliable switching, inline blade fuses for circuit protection, and a compact adhesive push-button switch with color indicators for each light channel. The kit supports two light fixtures and provides measured lead lengths so you can plan routing on trucks, Jeeps, UTVs, ATVs and motorcycles.

How does the kit manage two-color light bars?

The harness separates amber and white outputs so each color can be powered independently or both can run together. Two distinct leads feed each light fixture and the switch panel lets you toggle channels with illuminated buttons.

• Dual-channel wiring: amber and white are routed separately
• Two relays ensure each channel uses a dedicated control circuit
• Push-button switch with green/red indicators for instant channel recognition
• Compatible with most 12V dual-color light bars

What protection does the kit provide against electrical issues?

Safety features are built in to reduce the risk of overcurrent and short circuits. Each channel is fused and uses a relay so the switch only controls the relays and does not carry the full current load.

• Two 15A inline blade fuses—one per channel—protect circuits from overload
• Relays isolate the vehicle wiring from the light current draw
• 16AWG wiring balances flexibility and current capacity for most LED light bars
• Clear connector housings and labeled leads simplify safe installation

Will it fit my vehicle and light setup?

The harness is designed for 12V systems across a wide range of vehicles and supports two light fixtures via separate leads. Measured lead lengths help determine whether routing to your light bar and battery will be straightforward without additional extensions.

• Designed for 12V vehicles: trucks, Jeeps, ATVs, UTVs, motorcycles and more
• Two output leads: first at about 8.5 ft, second at about 11 ft from the power source
• Standard automotive connectors fit common dual-color LED light bars
• Switch includes adhesive backing to mount without drilling (or mount conventionally)

How simple is installation for a DIYer?

Installation is intended for DIYers with basic electrical experience. The kit includes labeled connectors, an accessory pack and instructions; you’ll still need basic tools and possibly a few vehicle-specific mounting accessories.

• Push-button switch with adhesive tape for no-drill mounting option
• Plug-and-play style connectors minimize splicing where compatible
• Accessory pack and manual included for step-by-step guidance
• Relays and inline fuses reduce the need for aftermarket circuit upgrades

Who this is for: This wiring harness suits off-road drivers, weekend adventurers and vehicle customizers who want dependable control of amber and white light bar channels without complex fabrication. Choose it if you use 12V dual-color LED light bars on trucks, Jeeps, UTVs, ATVs or motorcycles and want a protected, organized wiring solution with a compact, illuminated switch.
