Abstract
Emergency vehicle signaling system wherein an emergency vehicle transmits an RF signal having a narrow cone calculated to be received in a second vehicle. The receiver for the second vehicle is equipped with an indicator in the form of a white light which blinks in order to alert the driver of the emergency vehicle that the RF signal which it is transmitting has been received by the second vehicle. Accordingly, occupants of the second or non-emergency vehicle are made aware of the presence of the emergency vehicle while the visual indicator confirms reception of the RF signal.
