ABSTRACT:
A "hands free" vehicle signal system for requesting drivers to dim their vehicles' bright headlights. One front and two rear signal lights are mounted on the exterior of a vehicle and when activated flash "on" and "off" in high intensity patterns. "Hands free" operation of the signalling system is accomplished by a spoken word or automatically by front and rear mounted photocells. The front and rear signal lights can be operated individually or concurrently. In the first aspect of the invention, the front and rear signal lights transmit "on and off" beams of the same intensity. In a second aspect of the invention the front and rear signal lights transmit alternating patterns of high and low intensity flashing beams. In a first operating mode, the pair of rear signal lights alternately flash "on" and "off" . In a second operating mode the pair of rear signal lights concurrently flash "on" and "off" to transmit a "thank you" message to a driver after he has dimmed his vehicle's bright headlights. The front and rear signal subsystems are automatically deactivated when either the vehicle's turn signal lights, brake lights or back-up lights become active.
