I have a 2001 X5 3.0
Original owner.

I recently started having a problem with one of my xenon headlights.
After about 10 minutes, the headlight will turn off.

But if I turn the lights off for a few seconds, then back on, it will come
on again. Usually for about 10 more minutes before the same problem
happens.

I changed the xenon bulb, but that didn't solve my problem.

Anyone have any idea what's wrong? My best guess is the ballast is bad.

Thanks.
