So my HID bulb burned out on the passenger side. I bought 2 new ones, put them in and tested them a couple times, worked fine. Went to a parking garage and when the auto lights came on passenger side out again. So Im thinking it was the ballast that is blowing bulbs. I think about this the entire time we are there. When we go to leave, start her up and both come on..... I made sure there was not a loose connection when I put them in. Any thoughts?
