Bright Headlights won't work

[Zandam]

When I change from dim to bright on my headlights, the lights go out!

This is a 94 Caprice Classic that was a state trooper vehicle.

IS this a cop thing or do I have a serious problem??

Thanks, Zandam

shouldnt be a cop thing...one of my highbeams is out, i just havent changed the bulb yet, maybe both of yours are out so try changing the bulb

My guess is it might be the headlight dimmer switch. Used to have the problem that sometimes when I changed from low beams to high beams, the lights would cut off like you said. Replaced the dimmer switch and no problems since.

Thanks for the ideas. I have replaced the bulb and no change. It sound like the dimmer switch is the right answer.

I have not changed one on the Caprice, will I run into problems with the air bag. I am assuming the dimmer switch is included with the turn signal, speed control etc. on the steering colum.

Thanks, again

There was probably a wig-wag unit installed. Look under the hood for a green wire running to the headlights. One of them is cut....
