My driver headlight bulb on my ap1 recently went out so i purchased some bulbs thinking it would be an easy fix but nope. After replacing the bulbs the driver side is still out. The driver headlight is full of condensation and i will be replacing soon but before i do i need to know why its inoperative. I was thinking maybe the headlight harness got really wet? or maybe the ballast? Any insight is much appreciated.

 

Need a lot more information here. Which bulb, for example (I'm guessing low beam)? What year car?
