Vehicle Braking Warning Apparatus
First Claim
1. An electrical operated vehicle deceleration warning device broadly comprising a deceleration sensor coupled into the circuitry of at least a vehicles rear hazard/indicator lights, the circuitry including triggering means, activated by the change in the forces of momentum acting upon and detected by the deceleration sensor, caused by deceleration changes in the vehicles speed, activation occurring at a first deceleration threshold predetermined and set within the device and resulting in the device sending a signal to at least one of the rear hazard/indicator lights of the vehicle to cause the light(s) to illuminate, for a first predetermined period.

Abstract
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.
