Wife's car. She comes home the other night and says she has a head light out. No, problem, told her I'd take care of it.
Swing by AutoZone and there are like 4 different bulbs that could fit it and a damn $200 Xenon bulb. I don't buy anything, this is a job for Google.
Pull up some BMW forum stuff and some YouTubes. Of course...super bad ass German Engineering means you have to take off 5 things to get to one light bulb.
I did what any loving and caring husband would do...fixed it redneck style.
