ABSTRACT:
A system for use in monitoring the operation of motorcycle brake and tail lights is disclosed which, upon determination that a brake or tail light is not operating properly to provide a warning light signal, automatically provides an alternate warning light signal which is highly visible to traffic following the motorcycle. Current sensors are used to determine whether electricity is flowing through the brake light and tail light circuits, or, alternately, whether there is an open circuit condition in one or both circuits which is indicative of a burned-out bulb. If the tail light burns out, control switching elements are used to supply current to the left rear turn signal light, the right rear turn signal light, and the brake light to illuminate them, thereby providing a warning signal at the rear of the motorcycle. In addition, if the brake light burns out, control switching elements are used to supply current to the left rear turn signal light and the right rear turn signal light, thereby providing a warning signal at the rear of the motorcycle.
