  • Patent number: 5926112
    Abstract: A new Emergency Vehicle Warning System for warning vehicles of the approach of an emergency vehicle. The inventive device includes a receiver which provides both a visual message warning of an approaching emergency vehicle but also an additional flashing indicator light. The receiver also provides an audible warning signal which is selectively controlled by a button on the receiver. An alternate receiver is provided which includes the pictures of a plurality of different emergency vehicles and a flashing indicator associated with each vehicle. When the receiver receives a signal transmitted by an emergency vehicle, the flashing light of the corresponding emergency vehicle on the receiver is activated, thus indicating what type of emergency vehicle is approaching.
