A question about A BMW 325i???

Hello.

I just bought a 2002 BMW and under the mirror inside the car, there is a red round thing, it looks like a lamp, but i'm not sure what it is. is it a part of the alarm system?

Thanks.

Yes, it's part of the alarm if your car has one and also if you don't have an auto dimming mirror you can twist this to dim the mirror.

Its just a light to deter potential thieves. Its part of the alarm system.
naw, i think it's the sunset sensor, it turns on your lights at the loss of sun light...

"i think"

best wishes- happy hunting!
