Warning system for detecting burned-out condition of automotive lamps

摘要

A warning system for burned-out condition of automotive lamps including brake lamps, high-mount lamps and tail lamps, includes a detection circuit for monitoring the lamps to produce a first signal indicative of the presence of a burned-out lamp, and for monitoring a brake-lamp switch and a light switch to produce a second signal when the brake-lamp switch is ON and a third signal when the light switch is ON. The warning system also includes a control unit which receives the first, second and third signals and determines the identity of the lamp group including at least one burned-out lamp, and an indicator which indicates the identity of the lamp group including at least one burned-out lamp on the basis of the determination by the control unit.
