It seems I am replacing one bulb or another (headlight, brakelight, turn signal, etc.) every couple of months. First my local mechanic gave me some mumbo jumbo about the bulbs being high output and didnt think it was an electrical problem (I have a 1999 323i- no xenon lights). Now after seeing me burn thru a few, he agrees there's a problem. I have an appt. with BMW on monday and am concerned its going to cost me hundreds in labor. They said that despite all the new computer diagnostics, they still troubleshoot electrical problems pretty much as they did 10 years ago. First, what is the normal life expectancy of these bulbs in hours/days,etc.? Second, is anyone aware of this being a common problem? Third, what can I do to make sure I dont get taken for a ride (no pun intended) by the bimmer dealer? Any advice would be most appreciated.
