On your classic Camaro, Firebird, GM Truck, etc., the weak link in your headlights is the fact that all of the current runs through the headlight switch and there is a voltage loss. The problem begins when you want to upgrade your headlights to newer style halogens which require more current. Under load, the switch can burn out and leave you in the dark! This relay kit changes the path of the current to bypass the headlight switch and protect it from burn out.
