I need someone's help! I just put in aftermarket lights ( Halo ring projector lights ) and everything was working fine then the right side passangpa side went our, just the low beams. I put a new bulb in and it didn't come on. So I checked the power connections and they all have power. What could be the reason they don't come on?

 

I assume that when you say you checked power connections, that you see power right where the bulb plugs in. So in saying that, I will not go into the details of the factory circuits... Check the contacts on the harness where the bulb plugs into.
