Abstract

The present invention relates to a brake lighting system that includes a light array which illuminates sequentially when a velocity measuring device, independent of the braking system, detects a change in velocity of the motor vehicle, and communicates the change in velocity to the array. The velocity measuring device includes, but is not limited to, a speedometer, an accelerometer, an odometer, an anti-lock braking system (ABS), or a global positioning system (GPS). The velocity measuring device produces velocity measurement data which is processed by a system clock, a velocity measuring device data interface, a pulse generator, at least two memory latches, a deceleration level detector, and a brake light interface in order to sequentially illuminate the brake light array.
