ABSTRACT:
The device is capable of providing an automatic and timely indication of any sudden deceleration in the vehicle to which it is fitted, for the benefit of drivers following behind. A signal proportional to road speed is suitably generated and relayed to a discriminator capable of distinguishing between acceleration and deceleration and, on sensing sudden deceleration, of switching on the stop lights by way of an independent circuit installed in parallel with the stop light circuit of the vehicle.
