Abstract
A brake light enhancer circuit which may be readily connected to the brake light circuit of a conventional motor vehicle causes the brake lamps to be flashed a predetermined number of times when the brake pedal is initially depressed and thereafter causes the brake lights to be steadily illuminated so long as the brake pedal remains depressed. If, however, a turn signal indicator has been activated before or during the application of the brake pedal, the brake light enhancer circuit does not flash the rear brake lamps, but rather illuminates them continuously as long as the brake pedal is depressed. The circuit is configured so that normal brake light operation will not be impaired upon misconnection to the vehicle or failure or any component of the brake light enhancer circuit itself.
