Possibly a security system activation light.
That light indicates the security system is working properly.
Blinking red light signifies alertness or danger.
That is perfectly normal. It keeps theives away and is a security light.
It sounds like an anti-theft indicator light. The blinking light means that the security system is active and is functioning properly.

If there's a red blinking light on the dash by the Hazard switch, yes.
The blinking red light under the windshield on the driver side indicates that the car has not been locked with the key fob. Using the key fob to arm the theft alarm system turns the red light continuously on. In other words, the blinking is to remind the driver that the car is not locked (but will also be visible to any passerby, which is really a dumb feature of the car...why advertise the fact that the alarm system hasn't be activated?).
The blinking red light in the dashboard is an indicator that your anti-theft security system is armed and working.
The red light blinking on your device's motion sensor indicates that it is detecting movement or activity in its vicinity.
A blinking red light is the adapter's way of informing you of a low battery.
