Nilight 14AWG Remote Wiring Harness Wireless Strobe Switch

Nilight’s 14AWG remote wiring harness is a 12V, 20A one-lead kit with a wireless 4-mode strobe switch and a 12 ft extendable cable designed to power two light bars up to 300W.

This compact wiring harness package combines a handheld wireless controller and a dash-mounted rocker switch with indicator lights, a sealed power relay, fuse protection, and all the connectors needed to install strobe or warning light bars on most 12V vehicles. It’s intended to simplify wiring for auxiliary light bars while giving both local and remote control over on/off and four flash modes.

What controls and modes does the Nilight harness provide?

The kit includes two control options: a dash rocker switch with red and green indicators and a wireless remote with four selectable modes. You can toggle power on/off or choose steady, fast flash, or slow flash patterns from the remote.

• Rocker switch with illuminated red/green status lights for quick visual confirmation
• Wireless remote offering on/off, fast flash, slow flash, and steady on
• Remote range suitable for typical vehicle use (keep line-of-sight for best results)
• Durable buttons designed for frequent use and outdoor conditions

How does the harness protect the electrical system?

Safety features include a power relay and blade fuse protection to guard against overloads and short circuits. The harness ships with spare fuses and a sealed relay to help prevent failure from vibration or moisture exposure.

• Inline power relay handles switching and isolates accessory load from the vehicle’s switch circuit
• Blade fuse installed and two extra blade fuses included for quick replacement
• Load rating up to 300W total — compatible with dual light bars within that limit
• Neatly bundled wiring and heat-shrink connectors reduce exposed splices

What are the wiring and fitment details I need to know?

This is a single-lead harness with a 12 ft extendable main cable and one set of light output connectors capable of powering two lights in parallel. It’s designed for 12V electrical systems; 24V systems require replacing the relay with a 24V version before installation.

• 14AWG wiring with black negative and red positive leads; 12 ft main harness for flexible mounting
• One lead output that can feed two light bars up to a combined 300W
• Includes 4 connectors and a wiring diagram to streamline installation
• Swap relay for 24V vehicles — do not connect to 24V without changing relay

How easy is installation and what’s included in the box?

The harness arrives with pre-crimped connectors and a clear wiring diagram to speed up installation for DIYers or professional installers. You’ll find all necessary spare fuses and basic connectors to complete a standard auxiliary light setup.

• Package contents: 1 wiring harness kit, 3 blade fuses, 4 connectors, and 1 wiring diagram
• Pre-assembled relay and switch reduce on-vehicle wiring time
• Suitable for jeeps, ATVs, UTVs, cars, motorcycles, boats, yachts, and trailers with 12V systems
• Professional crimping or soldering recommended for permanent, weatherproof joints

Who is this for? The Nilight 14AWG 12V 20A remote wiring harness suits vehicle owners and installers who want a reliable, protected way to add strobe or auxiliary light bars without running complex custom wiring. It’s ideal for off-road enthusiasts, fleet vehicles, marine hobbyists, and service vehicles that require quick remote strobe control and built-in circuit protection. If you operate a 24V system, plan to replace the relay or choose a harness specified for 24V before installing.
