Nilight 3-Gang 16AWG LED Light Bar Wiring Harness Kit — 12V Switch Panel, Relay & Fuses (Blue LEDs, 6 Leads)

Nilight's 16AWG 3-gang LED light bar wiring harness is a ready-to-install 12V switch panel kit that safely powers up to six LED pods or light bars while protecting circuits with relays and inline fuses.

This harness combines a laser-etched three‑gang rocker switch panel with heavy‑duty 16AWG stranded wiring, a power relay, inline blade fuses and five‑pin toggle capabilities to make controlling auxiliary lighting on cars, trucks, ATVs, boats and RVs fast and dependable. The kit simplifies wiring multiple lights to a single dash-mounted control bank, letting each switch operate an individual circuit while delivering up to 180W per circuit and 540W total.

What components come with the Nilight 3‑gang wiring harness and how do they fit together?

The kit includes a prewired 3‑gang rocker switch panel with illuminated blue indicators, a heavy‑duty harness using 16AWG stranded wire, a relay, inline blade fuses and spade connectors. Wiring is grouped into six load leads (two per switch) so you can run two lights per circuit or route lights to different vehicle zones.

• 3‑gang laser‑etched rocker switch panel with blue indicator lights
• 16AWG stranded wire harness and 5‑pin relay
• Inline blade fuses and spade connectors for quick termination
• Six load leads (two per switch) to connect up to six LED fixtures

How much power can each switch handle and what protection does the kit include?

Each switch circuit is rated up to about 180W, and the complete harness supports up to 540W when all three circuits are used within specifications. Overcurrent protection comes from inline blade fuses and a relay that isolates the dash switches from high current draw, reducing stress on switch contacts and wiring.

• 16AWG wire rated for heavy loads and durability
• 180W per circuit, 540W total load capacity
• Blade fuses placed as the first defense against short circuits
• Power relay separates switch control from high current path

Is this harness compatible with my vehicle and my LED lights?

The harness is designed for 12V systems and fits most cars, trucks, ATVs, UTVs, motorcycles, RVs and marine craft that use a 12V battery. If your vehicle uses a 24V electrical system, swap the included 12V relay for a 24V relay to ensure correct operation. Check your light wattage and total draw to stay within the harness rating.

• Works with standard 12V vehicle electrical systems
• Suitable for LED pods, light bars and auxiliary fixtures
• 24V systems require replacing the relay with a 24V version
• Match combined wattage to the 180W-per-circuit limit

How easy is installation and what setup options does the harness offer?

Installation is straightforward for anyone familiar with basic vehicle wiring: mount the switch panel, connect fuse and battery leads, run the six load wires to your lamps, and secure ground connections. The six‑lead layout allows flexible placement—two lights front, two rear, two interior—or any combination you prefer, with each rocker controlling its own pair of leads.

• Plug‑and‑play style spade connectors for fast hookup
• Pre‑mounted switch panel with laser‑etched legends and blue LEDs
• Flexible routing: separate circuits for different vehicle zones
• Durable switch tested for thousands of actuations

Who is this for: The Nilight 16AWG 3‑gang wiring harness is ideal for DIYers, mechanics and fleet operators who need a tidy, protected way to add multiple auxiliary lights to a 12V vehicle. Choose this kit when you want a compact dash control bank, strong wiring and built‑in relay and fuse protection for headlights, light bars, work lamps or multiple LED pods without redesigning your vehicle’s electrical system.
