Abstract
An electronic vehicle slow-speed warning system operable automatically to activate the vehicle stop or brake lights if the operator neglects to do so while the vehicle is moving forwardly below a predetermined speed. Both the vehicle backup and stop lights are activated during backward travel at any speed. The warning system is designed for installation in conventional motor vehicles and is constructed entirely of solid state components free of moving parts. The system is selectively operable with either a frequency or optical speed signal sensor and with or without a micro processor.
