Nilight 12V Rocker Switch Panel Wiring Harness — 2-Gang LED Switch with Relay & Inline Fuses, 180W/circuit

The Nilight 12V On/Off rocker switch panel wiring harness kit is a ready-to-install 2-gang control system that lets you power and protect two separate 12V light circuits with LED indicators, relays and inline fuses.

This compact harness bundles heavy-duty wiring, a dual rocker switch panel, relay protection and blade fuses so you can add off-road lights, spotlights or auxiliary accessories to cars, trucks, ATVs, UTVs, RVs and boats with minimal wiring work. The included 16AWG stranded wire supports up to 360W total (180W per circuit) and the kit is set up for straightforward, reliable installation: connect the power, ground, and each switch output to your lights and the system manages switching and overcurrent protection.

How does the harness protect my lights and vehicle wiring?

The harness uses a dedicated power relay and inline blade fuse to prevent overcurrent and shorts from damaging the panel or your vehicle’s wiring. Each circuit is fed through the relay and protected at the first point of connection, minimizing risk in real-world use.

• Heavy-duty 16AWG stranded wire for robust current handling
• Inline blade fuse protects against overload and short circuits
• Power relay reduces direct current through the switch, extending switch life
• 180W per circuit rating ensures predictable load planning

What lights and vehicles are compatible with this kit?

This Nilight harness is designed for any 12V battery system: cars, trucks, motorcycles, boats, RVs, ATVs and UTVs. For 24V systems you can still use the panel if you replace the 12V relay with a matching 24V relay.

• Works with 12V LED light bars, spotlights, fog lamps and auxiliary accessories
• Suitable for automotive, marine and powersport applications
• Not pre-configured for 24V—relay swap required for higher-voltage systems
• Two switches control two independent circuits for flexible setups

How easy is the installation and what’s included?

Installation is straightforward for anyone familiar with basic vehicle wiring. The kit includes everything you need for a typical two-circuit lighting setup and uses common connectors for quick hookups.

• 1 x 2-gang wiring harness with built-in relay and LED rocker switches
• Blade fuses and spade connectors included for immediate use
• Laser-etched switch face resists wear and the LED indicator lights when each circuit is active
• Switch durability tested to 5,000 presses for dependable operation

How should I plan load and placement for the switches?

Balance your loads so neither circuit exceeds 180W and route wiring away from heat and sharp edges. Mount the switch panel where it’s easy to reach and visible, and secure the relay near the battery for best performance.

• Keep each circuit ≤180W to remain within rated capacity
• Run positive supply to relay close to battery; ground to a solid chassis point
• Use included connectors and fuses; replace fuses with correct ratings if needed
• Label or map circuits (front/back, left/right) before final mounting

Who is this for? This Nilight wiring harness kit is ideal for DIY vehicle owners, off-road enthusiasts, marine hobbyists and installers who want a compact, protected way to control two separate 12V lighting or accessory circuits. It’s designed for users who need a durable switch solution with LED indicators and built-in relay/fuse protection without complex fabrication or custom wiring harnesses.
