I have an '01 330ci. The previous owner had HID headlights and fog lights installed. Ever since I've owned the car (3yrs), I have had issues with the driver-side blinker burning out. I have replaced it 5-6 times, and that number would probably be higher if I didn't wait so long to replace it when it goes out. I also noticed that the fog light on that side does not stay on- it turns on, but then shuts off after a few minutes. I have no idea if these issues are related. I have solved the fog light problem by just not using my fog lights, but I need my blinker!
Any idea why that blinker bulb burns out so often? Do you think it's related to the issue with the aftermarket fog light?

Thanks!

My first thought would be to check the voltage going to the blinker bulb, if it's to high there's your problem.

I doubt this is your issue because I trust you when you say the bulb burns out but I'll throw it out anyway. My front passenger turn signal goes out every 6 months it seems. The bulb doesn't actually burn out though, seems to be a bad connection because I remove the bulb and reinsert it and it works for another 6 months. The bulb and connector both look good; I don't see corrosion. I've even put a dab of dielectric grease on the tip of the bulb but it still seems to happen.

Um dielectric = insulating material or a very poor conductor of electric current. Not sure how good of an idea this is.

I had burned connectors that would cause a bulb out warning and rapid blink when I purchased my car. Might not be a bad idea to do a through inspection of the bulb housing and replace if necessary.

Good luck!
