High Beam Problem

I believe there is a circuit breaker built into the headlight switch. When there is too much of a load, it starts to cycle which keeps the lights from going completely out.

First thing to do is make sure you aren't using headlights with too much wattage. Use only standard halogen bulbs, not the high output ones.

If the lights are fine, then replace the switch. Shouldn't be more than $10 or $20 at the local parts store.

You must have higher wattage than stock highbeam headlights. This happened to my dad's '78 T/A when he switched to bright Ciebie headlights. I think he solved it by adding a relay in the highbeam headlight circuit.

There is a circuit breaker built into the headlight switch and the switch may be bad, or as stated you are using the wrong headlights.

European lighting standards are different than the US ones :).

Umm, Mike: Jan lives in Norway so parts aren't just around the corner for his type of car. LOL. (But should be available).

I know Norwegian folks like Chevy products :), and the T/A uses the same parts as some older Chevy products where are semi-popular there :).
