Hello I'm new member in this forum, i'm from Spain, sorry for my bad english, I try to learn.
I have a problem in the low beams. Recently my alternator broke, it produced 16v, from that moment on when I turn on the low beams only one works for me, when I turn on the high beams all four work which means that it is not the bulb. I have checked the fuse box and everything is ok. It does not occur to me that it can fail, can someone advise me? Thank you

 

Hi Blue84Spain, welcome to TGO !

As to your question, the outermost two headlights on your Camaro have two filaments in them, a low beam and a high beam filament. Meaning that yes, you do most likely have a low beam filament burnt out in the headlight that won't light on low beam. Replace that bulb and I'll bet your problem goes away(make sure to buy the correct bulb type H4656)

 

Thanks for the welcome and the answer. Actually, I already found the problem, the two filaments are fine, what is wrong is the cap, the contact looks a bit sulfated and the plastic is somewhat melted, in some points it makes contact and it shines but in other points it does not give light. 👍
