Nilight Wiring Harness Kit 14 AWG 2 Leads – 12V, 5-Pin Rocker Switch, Relay & Inline Fuse for LED Light Bars

Overview

Meet the Nilight Wiring Harness Kit, a rugged solution designed for 12V lighting setups on a wide range of vehicles. Built with 14 AWG stranded wire, the harness handles up to a practical load while remaining flexible enough for tight installs. The first line of defense includes a power relay and an inline blade fuse, helping safeguard circuits from overcurrent and short events as you power your LED light bar or auxiliary lighting.

The kit features a 5-pin on-off rocker switch (SPST) with built-in LEDs that glow softly to help you locate the control in the dark. The nylon jacket wraps the wiring in a durable, high-temperature resistant sheath, providing safety, flexibility, and long‑lasting performance in real-world environments. Two output leads offer the option to run two lighting fixtures with a single, tidy wiring path, simplifying connections on the go.
