Abstract: A motor vehicle taillight employs light emitting diode (LED) technology, versus traditional incandescent lighting, to the sequential illumination of LED arrays, based on the nominal time it takes for LEDs to turn on and off. Separate or combined input signals from the brake, the turn signal blinker, and the rear marker activate controller subsystems to sequentially illuminate and deactivate LED arrays located within separate sections of the taillight. Significant benefits, such as lower power, cool burning, and long lasting bulbs result. In addition, the sequential LED array illumination design adds an intriguing effect, creating a marketable, visual appeal.
