3-series doesn't have that...
the grossly oversized red thing on the base of the 3-series (and other Bimmers') rearview mirror is the blinking LED for the alarm system. Yes, the E-class, M-class, S-class, etc. all have LEDs at the base of the mirror which are supposed to dimly light up the centre console at night. However, I'm not sure if the C-class has it (didn't think to look!) but it very well could.<p>h24-76-41-118.vf.shawcable.net
