ABSTRACT:
A device is provided, associated with the accelerator pedal of motor cars adapted to cause the lighting of the brake lights shortly before the brake pedal is applied in case of braking in an emergency. In one version of the device, it comprises a bellows mounted on the accelerator pedal. During normal driving, the bellows is pressed down to minimum volume thereof. When abruptly released, a sub-pressure is developed which is used to momentarily lift a metal flap which closes the brakelights circuit. The lights remain on until the light circuit is taken over by the brake pedal switching circuit. According to another version, the operation is based on the relative abrupt movement of a magnetic core surrounded by an induction coil. The electromotive force will generate a current effective to close the brakelights circuit.
