LED Light Wiring Harnesses & Accessories

Power your auxiliary lighting with Primelux LED light wiring harnesses and relay kits. Designed for trucks, tractors, RVs, utility vehicles and off-road applications, our harnesses provide an organized connection between the battery, switch and installed lights.

Choose from 1-lead and 2-lead relay harnesses for common auxiliary-light installations, or an H4 relay upgrade harness for compatible headlight systems. Available configurations include heavy-duty wiring, fused relay protection, illuminated switches and weather-resistant connectors, depending on the model.

Check wire gauge, lead count, switching configuration, fuse rating and connector type before selecting a harness. Looking for compatible lights? Explore our LED work lights for vehicle and equipment applications.
