No lights when you put bright lights on

[WeBeCamping2]

Driving home one night in our 2003 Challenger hit the bright light and the head lights whent out took bright light off and head light came back on..... anyone has any suggestion what this could be ?

Just a guess, both bulbs have burned out bright light filaments?

Bad headlight relay?

Bad dimmer switch?

Without much understanding of electricity, you should be able to isolate your problem. Using one of those "ice pick" style 12 volt testers that you can buy in an auto parts store, you could take the plug off the back of headlight (or the high beam light if it is a 4 bulb setup) and probe the connection to see if 12 volts is present in the high beam position. If not, you are back to the suggestions of the other posters, the switch or the relay. If I were a betting guy, I'd bet on the relay. BTW, when I use the ice pick style tester, I often have use another piece of wire on the ground lead to get me to a good ground source on the chassis. The wires provided on those testers are just too short much of the time.

A bad ground is another possibility.

I ran into this same scenareo the other day on a stock unit. Found a bad pin connection on a multiple quick connector. Does the bright light indicator come on on the dash? I doubt is it the relay since the light that are working do switch on and off.
