I am having a problem with one of my Xenon-Headlight on my 2005 325ci Coupe. Okay I change out the bulb, igniter and ballast the light will not come. The passengers side headlight is working so I switch out the passengers side with the driver side and it work. So If I plug in the drive side first the light work and plug in the passenger side it also work. So both lights will work but as soon as I turn the light off and wait about 20 mins then turn them back on the passenger side is the only one come on. So what is my problem with the driver side?
