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?
