Headlight
 

Headlight on my 2003 m3 sometimes tells me it is out and then other times it works fine. Do I need a new bulb or is something else going on. My husband got pulled over and we have to prove it works in 9 days. Thanks
Also if anyone knows why sometimes my heat/ac fan works only on occasion that would be great too:)

Sounds like the bulb is on its way out but to make sure, swap the bulbs from side to side. If the problem switches sides, then you need a replacement. I recommend replacing them in pairs so they match in color, light output and lifespan.

Thanks for the info...Can we switch them ourselves?
