most likely the bulb
It's most likely the bulb. I would try switching them around from one side to the other to see if the problem persists. If the problem moves with the bulbs it's probably a bulb issue. Otherwise the ballast might be getting weaker. The igniter is a non-issue in your case, as long as it starts the igniter is doing it's job.
Hopefully your car is under warranty, if not you're looking at a pretty penny for OEM bulbs. Might want to consider aftermarket D2S bulbs.
Good luck.
