Power will be drawn directly from your battery, eliminating voltage drops and ensuring headlamp system reliability.

The upgrade kit installs easily in 5-10 minutes without any cutting or splicing. Simply plug into your factory headlamp sockets, attach positive connectors to battery terminal and ground wires to the body of your vehicle. Two 30 amp relays provide added protection for your headlamp switch and wiring harness.
