You can download the owners manual for your car for free by registering in the Owners Circle area of the BMW NA website.

Yes, it blinks when the factory BMW alarm is activated. It's often called the "clown nose."

I'd also recommend reading the manual, which has lots of useful info to maximize your enjoyment of the vehicle.
