Re: One More Headlight Relay Thread

62 Short,

The problem is that without relays all the current for the headlights has to pass through the headlight switch. It is not made to carry the current of the bulbs we like to run nowadays (11 amps on high beam for me). With the relays the headlight switch carries only 100 milliamps to operate the relays. The relays are good for 30 amps each. The stock wiring is a little small for the high amp modern bulbs as well so it is good to upgrade the wire size while you are at it.
