Abstract:
1. A solid-state accelerometer warning module for motor vehicles having a power supply with a light illumination voltage level, said module having, at least one accelerometer responding to the variable speed of the motor vehicle, a microprocessor having a memory for storing an algorithm controlling the operation of said microprocessor and a calculation means responsive the algorithm for generating a first variable frequency illumination level control signal representing the deceleration rate of the motor vehicle, wherein the improvement comprises: a first antenna mounted to the front of the motor vehicle; a receiver electrically connected between said antenna and the module, said first antenna responsive for receiving a pulse rate control signal from another motor vehicle and inputting said received signal into said microprocessor; a transmitter electrically connected to said microprocessor for transmitting said first variable frequency illumination voltage level control signal; and a second antenna mounted to the rear end of the motor vehicle for transmitting said voltage level control signal from the motor vehicle wherein said antennas are optical sensors and transmitters.
