Headlamp Relay Harness Kit for 1947-91 Chevy Truck
Sends higher amperage to headlamp, handles higher wattage bulbs, cures dim lights. Also cures headlamp switch failure by bypassing current through switch and drawing current directly from battery. Original switch activates relays to turn headlights on. Used on single headlamps only and used for aftermarket headlamps.
Used this harness with 54-008 Halogen lights on a 55 GMC Series 1 and its perfect. With a little modification I have it wired into the harness for a 79 Trans Am Steering column and the relays hidden out under the radiator support. Plenty of wire to get from one side of the truck to the other.
