Abstract
A system for warning an occupant of a non-emergency vehicle of the approach of an emergency vehicle has a means for transmitting a signal, installed in the emergency vehicle, and a means for receiving the signal, installed in the non-emergency vehicle. The receiver is integrated into the electrical system of the non-emergency vehicle so that it is energized whenever an ignition system of the vehicle is engaged. When a transmitted signal, preferably a radio frequency signal, received by the receiver has a strength that exceeds a threshold strength, the receiver causes at least one of a visible or audible indicator in the non-emergency vehicle to be activated and remain activated as long as the signal is received at a strength above the threshold level. In many embodiments, the transmitter is activated anytime the emergency lights on the emergency vehicle are activated.

14. A method for warning an occupant of a non-emergency vehicle of the approach of an emergency vehicle, comprising the steps of:
-
providing the emergency vehicle with a means for transmitting a signal, the transmitting means selectively activated by an operator of the emergency vehicle;
providing the non-emergency vehicle with a means for receiving the signal, the receiver being integrated into the electrical system of the non-emergency vehicle such that the receiver is energized whenever an ignition system of the vehicle is engaged; and
configuring the receiver so that it transmits a signal to the electrical system of the non-emergency vehicle whenever the received signal from the emergency vehicle exceeds a pre-determined threshold strength, the signal transmitted to the electrical system so long as the transmitted signal remains above the threshold strength.
