This HID Xenon Controller Relay Wiring Kit with Waterproof Switch provides a secure, vehicle-ready solution to power auxiliary lights from your 12 V electrical system.
Ideal for adding roof, bumper, or under-hood light bars to trucks, SUVs, or ATVs. The kit lets you control new lights with the original car switch or the waterproof switch, while protecting circuits from shorts. Do not connect high-current lights directly to the factory wiring; the relay prevents overload.
-
Waterproof switch and weatherproof harness with self-locking terminals to minimize short circuits.
-
Two-channel control: Each switch group can control two light bars, allowing flexible operation.
-
Direct wiring: red positive lead with fuse to the battery; black to battery ground; switch feed from a convenient point.

Relay-based control keeps high-current lights separate from the factory switch circuit.
