ABSTRACT:
A system for the protection and safety of cars, passengers and pedestrians is described, adaptable to be installed in automotive vehicles having a gas pedal, a brake pedal and a battery, such as cars, tractors, trailers, trucks, buses, and the like. The system consists of a green light accelerator circuit which is energized when the driver presses the gas pedal, closing the contacts of its relay and lighting up its green light focus and is disenergized when the gas pedal is released opening the contacts of its relay so its green light focus goes out; a red light brake circuit which is energized when the driver presses the brake pedal, closing the contacts of its auxiliary relay and lighting up its red light focus, and is disenergized when the brake circuit is released, opening the contacts of its auxiliary relay so its red light focus goes out; and a white light sensor circuit which is energized by light entering the white light sensor, which is preferably covered by a small plastic tube, closing the contacts of its relay and lighting up its white light focus, and is disenergized when the sensor is no longer stimulated, opening the contacts of its relay so the white light focus goes out; and a first, second and third housings for housing the green light accelerator circuit, the red light brake circuit, and the white light sensor circuit.
