About 2 or so years ago I started to notice my night driving was becoming unpleasant and unsafe due to the fact that my headlights were losing output. After replacing the plastic lenses new from BMW I then went on to buying new bulbs thinking that would make a diff. It didn't. 10-12-12 today my lights are yellow/foggy on the inside like smoke has made the lenses opaque and my output is barely seen, I looked on the back where the bulb is inserted and it sure looks brown in there, I get more light reflected on the ground when I turn my turn signals than I do on the headlights. After going online and searching, my car came from facotry with a defect zkw xenon headlight system, which 99% of the zkw headlight owners of e46 sedans found online have the same issue, all you have to do is google "e46 zkw burnt bowls" . I have a 4 month old little girl, I cannot imagine driving with her in the car on a rainy night and my concern is now my baby. I can send you pictures if needed please, thank you for reading and I appreciate your help.
