Abstract
A system for flashing a plurality of light sources, such as the headlights, taillights, brake lights and/or turn signal indicators of an automotive vehicle which includes a plurality of light switching circuits wherein one light switching circuit is associated with each light source. Each light switching circuit is responsive to a predetermined input signal to switch its associated light source between an on and an off condition. A microprocessor has a plurality of output signal lines wherein one output line is electrically connected with each light switching circuit. The microprocessor is preprogrammed to generate the predetermined input signals to the light switching circuits on its output signal lines in a predetermined sequence.
Claims7
A system for flashing a plurality of light sources comprising:
- a plurality of light switching circuits, one light switching circuit being associated with each of said light sources and responsive to a predetermined input signal to switch its associated light source between an on and an off condition,
- a microprocessor having a plurality of output signal lines, each of said output signal lines being electrically connected with each light switching circuit,
- means for programming said microprocessor for generating said predetermined input signal on said output signal lines in a predetermined sequence,
- means tier determining the ON/OFF condition of at least one of said light sources and for generating a status signal representative thereof, and means for electrically coupling said ON/OFF condition signal as an input signal to said microprocessor, wherein said coupling means comprises an optical isolator.
