Abstract
Abstract An emergency vehicle warning system including a plurality of directional receivers disposed within each of the driver's vehicles. The receivers are directed in opposing directions to span 360 degrees. Each of the receivers is capable of receiving a single radio frequency. A directional display and speaker are disposed interiorly of each of the driver's vehicle. The directional display and speaker are in communication with the directional receivers. An omni-directional receiver is disposed within each of the traffic lights in communication with an operating light system thereof. The omni-directional receiver is capable of receiving a same radio frequency as the four directional receivers. The directional receivers in each traffic light in communication with an operating system there is capable of receiving a second frequency when activated. A transmitter is disposed within the emergency vehicle. The transmitter is in communication with the directional receivers drivers vehicle 12 and the omni-directional receiver whereby the transmitter generates the primary and secondary radio frequencies and directional receivers in the traffic light will receive the secondary frequency upon activation.

Claim 1
Independent Claim
207 words
An emergency vehicle warning system for notifying all drivers that an emergency vehicle is approaching, wherein the system works with the driver's vehicles and with traffic lights at intersections, the system comprising, in combination: four directional receivers disposed within each of the driver's vehicles, the receivers being directed in opposing directions to span 360 degrees, each of the receivers being capable of receiving a single radio frequency; a directional display and speaker disposed interiorly of each of the driver's vehicles, the directional display and speaker being in communication with the four directional receivers, the directional display including illuminatable direction arrows; an omni-directional receiver disposed within each of the traffic lights in communication with an operating light system thereof, the omni-directional and directional receiver being capable of receiving a same radio frequency as the four directional receivers, the omni-directional receiver including an audible alarm, the directional receiver being capable of receiving a second radio frequency; and a transmitter disposed within the emergency vehicle, the transmitter being in communication with the four directional receivers and the omni-directional receiver, whereby the transmitter generates the single radio frequency to a secondary transmitter disposed in the emergency vehicle, the secondary transmitter being in contact with four directional receivers in the traffic light.
Claim 2
Dependent Claim
