The headlight alarms on my '05 955 has recently stopped working. I do not believe it is the speaker (replaced 2-3 years ago), because the chime still seems to be working when indicators are on, seatbelts unfastened, low fuel, etc. My guess is that there is another sensor that needs to be checked, but I don't know where to look. Much appreciation for any ideas about how to diagnose and hopefully fix! Cheers955
