Abstract
A brake light enhancer circuit which may be inserted into a conventional motor vehicle lighting system to provide a more eye catching braking or deceleration signal to following drivers. The circuit may be connected between the rear signal lamps, brake light switch and flasher in a conventional vehicle lilghting system. It may include a timer or pulse generator, a counter and a disable latch. In motor vehicles having a pair of left and right turn signal lamps and a pair of left and right brake lamps, closure of the brake light switch when the turn signal switch is in its neutral position will cause the brake lamps to flash on and off a predetermined number of times and to thereafter remain continuously illuminated. When the turn signal switch is moved to either its left or right turn position, the brake light enhancer circuit is disabled so that turn and brake light signals are conventional, thereby preventing confusion of following drivers.
