ABSTRACT:
A rear motor vehicle alerting bright light dimming signal and control system for alerting a driver of a vehicle behind a signalling 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. A control system permits the signalling system to operate only when the stop lights and turn signal lights of a signalling vehicle are inoperative. The signal system comprises one or more flashing lights mounted at the rear of a vehicle and a control circuit for operating the lights. In one aspect of the invention, a signalling light is mounted on a rear package tray in a common housing with an "eye level" stop light and, when operative, transmits a flashing high intensity beam of colored light to alert the driver of the rear vehicle. The control system has two states, a normally off state and an operating state wherein the signal light flashes for a predetermined time. In an alternate embodiment the signal lights are automatically activated by a bright light from a rear vehicle.
