ABSTRACT:
For use in warning motorist, especially those who are hearing impaired, of an approaching emergency vehicle, a new and useful invention comprises a transmitter which is installed into an emergency vehicle and activated upon an emergency run. A low frequency signal is sent out over the emergency vehicles original equipment antenna system and is picked up by motorist having a receiver unit mounted to their dash panel. The signal is processed into visual and audio warnings whenever a transmitting emergency vehicle is within close proximity to the receiving vehicle. The receiver is on full time when the motor vehicle is in operation thereby allowing suitable response time for motorist to take appropriate action in yielding to the emergency vehicle. The transmitter does however have an on/off switch as well as a visual and audio means for monitoring the transmitted signal.
