Sometimes one of my headlights goes on and sometimes it doesn't. (the upper bulb) The number of occurrences in which the headlight fails to turn on is increasing as time goes on. I assume that the bulb is fine, because if it wasn't then it would never work, rather than off and on. Could it have something to do with being lose, the wiring or bulb? I'm not sure. Help me out if you can.

 

Try to pushing the ballast in.

 

Thanks for the answer, how do I push the ballast in? What does it look like?
DIY?
Thanks!

 

im having the same issue, finally burnt out. I checked the fuses and bulbs so im guessing i need a new ballast?
