1. A velocity responsive battery and generator lighting system for a vehicle having a member rotatable at a velocity related to the speed of the vehicle, comprising:

  • a. generating means for generating electricity mounted on said vehicle adjacent said member and selectively switchable between an operating mode and an inoperable mode with respect to said member, said generating means being operable in said operating mode to generate a first predetermined potential in response to said member rotating at a velocity above a predetermined velocity, b. first light means mounted on said vehicle and electrically connected with said Generating means, said first light means being energized in response to said generating means generating said first predetermined potential, c. potential dividing means operable with said generating means for generating a potential lower than said first predetermined potential and proportional to the rotational velocity of said member, d. second light means mounted on said vehicle operable to be energized at a second predetermined potential, e. battery means for protruding said second predetermined potential mounted on said vehicle, and f. solid state circuit means being free of moving parts for interconnecting said second light means, said battery means and said potential dividing means and including solid state switching means for controlling said second light means between unenergized and energized conditions and means responsive to the potential generated by said generating means with said potential dividing means for controlling said switching means, whereby said second light means is unenergized upon said member rotating at a velocity above said predetermined velocity and said second light means is energized by said battery means upon said member rotating at a velocity lower than said predetermined velocity.
