Nilight 14AWG Remote Wiring Harness 12V 20A 1-Lead — 12ft Cable, Wireless Strobe & Relay Protection for Up to 300W

Nilight 14AWG Remote Wiring Harness is a 12V, 20A one-lead strobe wiring kit with a wireless controller, 12ft cable, relay and blade-fuse protection built for powering up to 300W of auxiliary light bars.

If you need a reliable way to operate strobe or auxiliary light bars from a dash-mounted rocker switch plus wireless remote, this Nilight kit brings the wiring, relay protection, connectors and extra fuses in a ready-to-install package. It’s designed to simplify wiring two light bars from one output lead while offering on/off and two flash-rate modes via both the switch and remote control.

How does the remote and dashboard switch work together?

The kit includes a rocker switch with red and green indicator LEDs and a separate remote with four control modes: on, off, fast flash and slow flash. Both the physical switch and the remote send control signals to the relay, so you can operate lights from inside the vehicle or wirelessly from a short distance.

• Rocker switch: illuminated red/green indicator for active status.
• Wireless remote: four modes — on, off, fast flash, slow flash.
• Relay control: accepts input from either switch or remote to toggle outputs.
• Redundant control: manual override works if the remote is unavailable.

What protection and load capacity does the harness provide?

This harness uses a power relay and blade-type fuses to protect against over-current and shorts. The wiring is 14AWG and the relay/fuse arrangement supports a combined light load up to 300W; two spare fuses are included for serviceability.

• 14AWG wiring: balanced for accessory lighting current up to rated load.
• Power relay: isolates control circuit from high-current output for safety.
• Blade fuses: protect against short-circuits; three fuses included total.
• Load rating: supports up to 300W of connected lighting equipment.

How do I wire it and what fits on the single lead?

The harness provides one set of light-output connectors on a 12ft extendable lead; the black conductor is negative and the red is positive. You can connect two compatible light bars to that single output as long as the combined wattage does not exceed 300W.

• Single lead output: designed to feed up to two strobe or light bars.
• Polarity: black = negative ground, red = positive feed to lights.
• Distance: 12ft cable gives flexibility for routing to front or rear mounts.
• Compatibility: made for 12V systems; swap relay for 24V applications only.

Who this is for: Installers, DIYers and vehicle owners who want a compact, protected way to add switchable strobe or auxiliary lighting to cars, trucks, ATVs, UTVs, boats and trailers. It’s ideal when you need both dash and remote control, simple wiring with one output lead, and basic circuit protection without running multiple dedicated power runs. If your vehicle uses a 24V electrical system, plan to replace the 12V relay with a 24V relay before installation.
