Re: Headlights cut out completely after hitting high beam dimmer switch

If you have higher wattage Halogens in the truck the dimmer switches don't survive well.

I put relays on both low and high beam circuts on my 71 to cut down on the load through the switch (s) After replacing the switch about every four or five months but I am running 55/100 H-4 bulbs.
