On most vehicles, the power to headlights is routed from the battery, to the vehicle wiring harness to the headlight switch, then back out to the headlights. This long route from battery to headlight caused a voltage drop and heat build up, resulting in dim headlights and failure to headlamp switches.
This headlight relay upgrade harness was designed to improve voltage to the headlights by using better, newer, shorter heavy duty wires and relays, directly powered by the battery.
