Looking for a ballast or igniter I think they may call it for my 06 STI I believe 04-14 will work fine. Let me know if you have one. It's the left headlight if that matters at all. Max 952-836-5078
Is it the thing on the bottom of the headlight housing? Mine stopped working about a year ago. There was moisture in the headlight. I cooked it in the oven at about 250f for a hour resealed the headlight no problems since. Got the moisture out of it. Subaru wants about $300 for one
