Hey you guys so as of a couple of days ago I've come across a problem with one of my headlights. I have an 82' camaro, and as you know there are four headlights. The two low beam engage when the brights are off and all four engage when the brights are on. Well when Im on the low beam, only one headlight turns on. My first thought was that the other low beam was dead but when you engage the high beams, all four work great. Could there be an issue with a relay connecting to that one light?

 

The low beam that's dead needs to be replaced.

The low beam lamps have two filaments. One for the low beam and the other for the high beam. When you switch from low to high beams the filaments also switch.

See the diagram posted on this thread:
