Actually that's kinda interesting. Instead of recognizing the lights or something you could create a communication of some sort where the officer's vehicle provides a key that the car can then authenticate that it's a real police officer making the pull over request. Heck you could even check with a police department system that the officer is on duty and in that area so a stolen police car or key couldn't be used.
