Any help and/or suggestions appreciated... My passenger side headlight is out, I got a new bulb and no such luck. I’m trying to diagnose the issue, without it costing me an arm and leg. I’m suspecting it could be the ballast, and thinking that I should order one. My colleague said he had a similar issue, but just opted to buy a whole entire headlight setup and replaced that completely.

 

Buy a used one off ebay, they are cheap. Plug your working one into the other side to test and make sure that's what the issue is.
