ABSTRACT:
A system for preventing rear end collisions is provided including a warning light housing with a transparent panel mounted to a rear of the vehicle. A distance detector is directed toward a rear of the vehicle. The distance detector is adapted to detect a distance from a following car. A bulb is provided for illuminating upon the actuation thereof. Finally, control circuitry is connected between the distance detector, bulb, a speedometer, and a battery of the vehicle. The control circuitry is adapted for receiving a speed of the vehicle from the speedometer and further to calculate a distance per speed value, whereby the control circuitry actuates the bulb only upon the distance per speed value being lower than a predetermined value.
