An electrically operated vehicle deceleration device for providing a warning to other motorists of the deceleration of a vehicle. The device is typically coupled into the existing electrical lighting system to operate at least the rear hazard/indicator lights. The device includes a terminal block which provides for the vehicle's battery to power the device via a regulated power supply. The terminal block connects the device to all the hazard/indicator lights of a vehicle via a deceleration sensor which in turn is coupled to triggering elements such as a programmable interrogation/activation microprocessor, which is programmed to provide triggering at two different thresholds of deceleration as detected by the sensor. A first threshold is provided when deceleration approaches 0.8 g-force and a second threshold when deceleration approaches 0.9 g-force. At the threshold levels the microprocessor signals a power output stage which provides for illumination, in different pre-selected modes, of the hazard/indictor lights.
