Don't risk an electrical fire or a dead battery by cobbling together cheap wire and tape. Power your off-road lights the right way with a heavy-duty, fused harness designed to handle the load.
Dual Output Heavy-Duty LED Light Bar Wiring Harness with Marine Grade Switch (300W Capacity)
Wiring up off-road lighting can be a headache, but this GENSSI Dual Output Harness makes it a professional, plug-and-play affair. Designed to support the high-current demands of modern LED setups, this harness is capable of powering two light fixtures simultaneously (up to 300 Watts total). Whether you are running a pair of ditch lights on your A-pillars, two spotlights on your bumper, or a single massive 50-inch bar, this system handles the power safely and reliably.
The core of this harness is a durable, vibration-resistant 12V relay. This relay acts as the heavy lifter, taking the high-amperage load directly from the battery to the lights, keeping that dangerous current away from your dashboard switch. Speaking of the switch, this kit includes a premium Marine Grade LED Rocker Switch. It features a standard mounting size (1.41″ x .86″), meaning it fits perfectly into the factory switch knockouts found on most modern Jeeps, UTVs (Polaris RZR/Can-Am), and trucks, giving you a factory-installed look rather than a cheap toggle switch dangling under the dash.
While engineered for instant Plug-and-Play compatibility with GENSSI products, this harness is universally compatible with any 12V LED light bar on the market. If you are running Rigid, Baja Designs, or generic lights, simply snip the GENSSI connectors off the end of the harness and hardwire it to your lights. With approximately 9 feet of wiring to the lights and 9 feet to the switch, you have plenty of length to route wires cleanly through your engine bay and firewall.
Why You Need This Upgrade
- Dual Output Capability: Pre-wired connectors allow you to control two separate lights (e.g., a pair of pods) with a single switch.
- Safety First: Features an inline fuse holder and a heavy-duty relay to protect your vehicle's electrical system from surges and overheating.
- OEM-Style Switch: The included Marine Grade IP67 switch fits standard 1.41″ x .86″ mounting holes, replacing blank dashboard panels seamlessly.
- Weatherproof Design: IP67 water resistance rating ensures the harness survives mud, river crossings, and engine bay washdowns.
- Universal Power: Supports up to 300 Watts of total draw, making it robust enough for almost any light bar setup.

Installation Notes
For GENSSI Lights: This is a direct plug-and-play installation. Connect the ring terminals to your battery and plug the Deutsch-style connectors into your lights.
For Other Brands: You can use this harness with any brand of light bar. Simply cut off the pre-installed output connectors, strip the wire insulation, and splice/solder the wires to your light bar's pigtail (Red to Positive, Black to Ground).
Switch Fitment: The switch face measures 2″ (50mm) x 1″ (25mm). Please measure your dashboard slot to ensure fitment, though this is the industry standard size for most aftermarket rocker switches.
