Xenon Issues

Hi guys, I have a bit of a unique situation. I've done a month of forum searching and can't find a situation similar to mine.

So last summer my left headlight was flickering. I bought khoalty bulbs and the problem went away for a month. When it came back I switched the igniters and saw the igniter was melting like there was a short. So I ordered a new one and the problem was fixed until about May. I got a tail light indicator on my dash in August that just turned out to be a bulb that burned out. So I was convinced it was the ballast. I ordered a kit from BavToys but they told me I'd lose my high beam function with one of their kits. I looked at the replaced igniter the other day and noticed a little bit of melting but nothing near the catastrophic failure of the old one.

So now I'm stuck. I'm gonna switch the ballasts today to see what happens, but does anyone have a clue as to what is wrong? Should I order another OEM ballast? Should I get new headlights altogether?? Any help would be appreciated.

Did your car come with OEM xenons from the factory? Also, does the headlight flicker if the engine is off?

Before buying new parts you should narrow down the cause of the problem. When the left side flickers again, switch bulbs. If left side still flickers, switch ballasts. If left side still flickers, switch ignitors. If the flicker problem happens on the other side when you swap a certain part, replace that part.

It could also be a ground issue in your tail light. (simple fix, search forums)

They are factory xenons. My car wasn't under the tail light recall but I may do it anyway. I just need a parts list (not that I can find one...). And I'm not sure about engine off. I'll do some testing today to see.
