Nilight 12V 2-Gang Rocker Switch Panel Wiring Harness Kit — Blue LED, 360W Total, Relay & Fuse

Nilight's 12V 2-gang rocker switch wiring harness is a ready-made kit that lets you control two separate LED light circuits safely and cleanly from a compact dashboard panel.

This kit bundles a durable two-switch panel, pre-wired 16AWG harness, relays and inline blade fuse so you can quickly add or upgrade auxiliary lighting on 12V vehicles. It’s designed to simplify wiring for LED light bars, fog lights or other 12V accessories while protecting circuits against overloads and shorts. The included switches are laser-etched and backlit in blue for easy visibility, and the wiring components are sized to support heavy-duty loads up to the harness’s rated capacity.

How does this wiring harness protect my lights and vehicle electronics?

The harness uses a relay-based design with an inline blade fuse so high current flows directly from the battery through protected wiring instead of through the switch. This reduces heat and wear on the switches and isolates the vehicle’s electrical system from accessory faults. The relay acts as the primary switching device and the fuse is the first line of defense against overcurrent and short circuits.

• 16AWG stranded wire for reliable current handling and flexibility
• Inline blade fuse included for circuit protection
• Power relay switches high current away from the panel switch
• Rated load: 180W per circuit, 360W total on 12V systems

What can I control with each switch and how many lights can I wire?

Each rocker switch controls its own output circuit, so the two-gang panel can manage two separate light banks or accessories independently. The harness has four output leads total (two per switch), which makes it easy to wire multiple lights or split a light bank between front and rear positions. This flexibility lets you create dedicated zones—like front driving lights and rear work lights—without additional panels.

• Two independent switches, each with two output leads
• Allows up to four individual light connections across two circuits
• Typical wiring: one switch for front lights, one for rear lights
• Works with LED bars, spotlights, fog lights and similar 12V accessories

Is the switch panel durable and easy to install in a vehicle dash?

The switch housing is built for repeated use and finished with a laser-etched pattern that resists fading. The panel’s blue LED indicators light when a circuit is active, improving visibility at night. Installation is straightforward for anyone comfortable with basic automotive wiring: mount the panel, connect the fused power lead to the battery, ground the harness, and run the output leads to your lights.

• Panel tested for at least 5,000 actuations
• Blue backlight shows active circuits for safe night driving
• Includes blade fuses and spade connectors for faster hookups
• Plug-and-play style wiring reduces custom crimping and soldering

Will this work on all vehicles and what about non-12V systems?

The harness is optimized for 12V systems common to cars, trucks, ATVs, UTVs, motorcycles, RVs and marine craft. It can support many vehicle types without modification, but it is not suitable for 24V systems unless you replace the relay with a 24V-rated relay. Always match the kit’s electrical ratings to your accessories and vehicle battery before installation.

• Designed for 12V batteries—cars, trucks, motorcycles, RVs, boats
• Not directly compatible with 24V systems without relay swap
• Use appropriate wire routing and grounding practices for safety
• Check total wattage to remain within the 180W per-circuit limit

Who is this for: This Nilight wiring harness is ideal for DIYers, professional installers and vehicle owners who want a tidy, protected way to add or manage auxiliary lighting. It suits anyone upgrading with LED light bars or multiple accessories on 12V platforms who needs independent control, clear illuminated switches, and built-in circuit protection for safer, cleaner wiring runs.
