Abstract:
An emergency deceleration warning apparatus utilizing a Reverse-Light in combination with a Brake-Light when a vehicle decelerates at a deceleration of 0.2 G or above, comprises:an electric power-source with high voltage side and a low voltage side, for providing the electric power energy, connected toa deceleration sensor for detecting a deceleration above 0.2 G comprising of:a package for holding a deceleration sensor circuit with forward and level markings;a magnet or adhesive or a set of screws for connecting the package to a vehicle in a horizontal level condition;a wire to connect to the electric power-source to the deceleration sensor circuit, for obtaining electric power to energize the deceleration sensor;a wire to connect to the Reverse-Lights from the deceleration sensor circuit, for delivering the electric power toa set of warning lights visible to following vehicles that includes:a set of Brake-Lights that indicates that the driver is applying the brakes, anda set of Reverse-Lights that indicates that the driver is using a reverse gear;an elongated sealed hollowed tube with a top end and a bottom end, with a length of up to 10 centimeters,a conductive liquid inside the elongated sealed hollowed tube, resting at the bottom end; two permanent conductive contacts located at the top end, andsuch elongated sealed hollowed tube is positioned inside the package pointing to the front end of the vehicle in an angle of 11 to 90 degrees up from the horizontal level position, and upon deceleration the conductive liquid proceeds up a slope along the interior of the elongated sealed hollowed tube until the conductive liquid reaches the top end, and creates an electric contact between the two permanent located conductive contacts at the top end and engages the deceleration sensor circuit.
