Abstract

A motor vehicle signalling system for requesting a driver of a vehicle behind another vehicle to dim his bright lights. The signalling system is low in cost, improves vehicle safety, promotes driver courtesy and is adaptable to all motor vehicle styles and models. The signalling system includes a flashing colored light mounted on the rear of the signalling vehicle and a control circuit for operating the flashing light. The signalling light is mounted in a common housing with an "eye level" stop light on a rear package tray and when operated produces a high intensity flashing beam of colored light to attract the attention of the driver of the rear vehicle. The control system has three states, a normally off state, an operating state wherein the signal light flashes for a predetermined time, and an operating state wherein the signal light flashes continuously. Alternate embodiments are disclosed wherein the signal light is automatically controlled and/or is located in a common housing with the vehicle'"'"'s other lights.

Claims

11. The vehicle headlight dimming signalling system described in claim 10 wherein said system is operative only when said vehicle'"'"'s headlights are operative.

12. In a motor vehicle of the type having a pair of headlights, a pair of combination stop and tail lights, an "eye level" stop light and a pair of back-up lights, a system for requesting a driver of a vehicle travelling behind another vehicle to dim his vehicle'"'"'s bright headlights comprising:

a pair of dedicated lights mounted at the rear of a vehicle, each of said lights being enclosed in a housing which is common with a back-up light of said signalling vehicle;

a manual control, said control having a driver operated switch for initiating a first operating state for flashing said signalling lights "on and off" for a predetermined time and a second operating state for flashing said signalling light "on and off" continuously; and

means for distinguishing said signalling light from said other lights of said signalling vehicle.

13. The headlight dimming signalling system described in claim 12 wherein said manual control is spring biased for returning said control system to an inoperative state when said driver operated switch is released.

14. In a motor vehicle of the type having a pair of headlights, a pair of combination stop and tail lights, an "eye level∞

stop light and a pair of back-up lights, a system for requesting a driver of a vehicle being a vehicle to dim his vehicle'"'"'s bright headlights comprising;

a pair of dedicated lights mounted at the rear of a vehicle in common housings with said vehicle'"'"'s back-up lights, said lights having an operative state wherein said lights flash "on and off" to request the driver who is operating a vehicle behind the signalling vehicle to dim the headlights of the rear vehicle;

an indicator light inside of said vehicle for informing the driver of the signalling vehicle that his vehicle'"'"'s signalling system is operative; and

means for distinguishing said signalling light from said other lights of said signalling vehicle.

15. In a motor vehicle which is adapted to selectively move in a forward direction and in a reverse direction and having a pair of lights mounted on the rear of the vehicle which are normally operative only when said vehicle is moving in said reverse direction, the improvement which comprises a means for flashing said lights "on and off" when said vehicle is moving in said forward direction to signal a driver who is operating a vehicle behind the signalling vehicle to dim his vehicle'"'"'s bright lights.

16. The headlight dimming signalling system described in claim 15 wherein said means for flashing said lights "on and off" comprises:

a driver operated control in the interior of said signalling vehicle, said control having an inoperative state wherein said signalling light is continuously off, a first operating state wherein said signalling light flash "on and off" for a predetermined time, and a second operating state wherein said signalling light flashes "on and off" for a continuous period of time, said control being spring biased to return said control from said first operative state to said inoperative state when said control is released by said driver;

a time delay operatively connected to said driver control for causing said lights to flash "on and off" for a predetermined time when said control is returned to said inoperative state;

a flasher unit operatively connected to said time delay to cause said lights to flash when said control is released by said driver.
