The Clown Nose (under your mirror) can be programmed by the dealer to blink, along with the parking lights flashing upon locking/unlocking, **giving the appearance** of an active alarm, which is all you need 99.9% of the time.Well, if it did not why would it have the red light on the rear veiw mior? and a red light on consult that blinks? It is a BMW 330i sport 2003.
