ABSTRACT:
A stop-light monitor device includes a source of current, a lighting circuit connected with the source and having a stop-light switch actuated by the brake pedal. The lighting circuit has incandescent lamps which are energized when the brake pedal is depressed. A magnetic reed switch is influenced to closed position by a permanent magnet, and is connected to control a solid-state switch which in turn controls a pilot light that becomes illuminated when the solid-state switch is closed in consequence of the reed switch being opened. A current-sensitive coil connected with the lighting circuit, opens the reed switch in response to normal energization of the stop lights, whereby the pilot lamp is energized. If a stop light burns out, the reed switch closes, opening the solid-state switch whereby the pilot light is extinguished, giving an indication of the malfunction.
