Nilight 16AWG Wiring Harness Kit 12V

This 3-gang wiring harness brings organized power control to auxiliary lighting on cars, ATVs, boats and RVs, with separate switches for up to three circuits and protection against overloads. It is intended for 12V systems and lets you operate multiple LED pods or light bars from a single panel, improving wiring safety and switch accessibility.

Key Points

The harness uses 16AWG stranded wiring, which supports higher loads for aftermarket lights and offers more durability than thin test leads. Each switch controls a separate circuit so you can run different light groups independently, such as front, rear and interior lighting. The rocker panel includes blue indicator LEDs and a laser-etched pattern that resists fading, and the switches are rated for repeated use with a manufacturer-stated test of 5,000 presses. ⚡️🚗

This kit also integrates a power relay and inline blade fuse as the primary protection against overcurrent and short circuits. According to the product details, load handling is generous enough for several LED pods, though if you plan on very large light bars, check the combined wattage per circuit. The harness is compatible with most 12V battery vehicles and can be adapted for 24V systems by replacing the relay with a 24V unit.

Usage Recommendations

Install the harness where switches are easily reachable and where the relay and fuses can be mounted close to the battery for better protection. For grouping lights, run two leads per switch as intended so each circuit handles its own set of lamps without sharing a feed. If your installation will exceed 180W on a single circuit, consider distributing loads across the three circuits or use a heavier gauge harness to reduce voltage drop.

When fitting on watercraft or exposed vehicles, route wiring clear of sharp edges and moving parts and use additional sealing or conduit where needed to prevent corrosion. For users converting to 24V systems, note that the relay must be replaced with a 24V relay before connecting to a higher-voltage supply. 🛠️🔧
