check the fuse. my dim headlight got me arrested. after pulling relays and such i found the right fuse was missing.

 

there is a fuse for each light at the fuse panel, check them first

Old Wal,

 

Please do not start a new thread when replying about the same problem. Just continue the thread by clicking the reply button at the bottom of the thread. This way information about the problem stays together.

I also had 1 dim light, and it turned out to be just the fuse.

It might be a bad filament in the bulb itself. I encountered the same situation about 5 months ago. The filament for the low beam had severed and its remains had become entangled with the high beam filament, which basically caused a short circuit. An easy way to check is to try plugging the bulb you suspect is bad, into the other headlight socket and see if it operates normally. If it does operate normally, then check the fuse. If not, you have about a five minute headlight bulb replacement job on you hands.
