some of them can get the transmitters to turn the traffic lights, they just put em in the front windshield and turn em on when they get a call

re-read please, signal emitters for the traffic light changing devices is what i said it might have been.
The device emits a radio wave to a receiver on the stop lights. Then the receiver changes the lights you are coming up on to green so the emergency vehicle doesn't have a red light and can get through the light faster.
