Plug n Play Spotlight Wiring Harness
Getting LED lights wired up doesn't need to be complicated. With a plug-and-play spotlight wiring harness, you can skip the cutting, soldering and head-scratching, and get your lights mounted and working in no time.
Our wiring harnesses are designed to make DIY installs as straightforward as possible. They plug straight into the back of your headlight using included H4 and HB3 adapters, connect directly to your battery, and feed power to your spotlights or light bars through industry-standard Deutsch plugs. Everything comes pre-wired with inline fuses, relays, and a flush-mount switch you can pop into your dash. No electrician required.
Whether you're mounting lights on the front for night driving or at the rear for camp lighting, there's a harness to suit. Forward-facing kits work on both positive and negative switched 12V systems, so they'll play nice with most vehicles without any fiddling. Rear lighting harnesses let you power worklights or camp lights from a rocker switch inside the cab. Both options use water resistant Deutsch connectors to keep moisture out and your setup reliable.
The included relays handle the heavy lifting so your lights get full power without overloading your vehicle's existing circuits. If you're running advanced setups like our Lethal Pro driving lights, there's even a harness with a low-profile remote controller that gives you 25 adjustable brightness levels and memory mode. It's all designed to plug straight in and get you back on the road.
Every harness is built with quality components that stand up to Australian conditions. Dust, water, vibration. They'll keep doing their job trip after trip.
