Flashing brake light system |
摘要 |
A vehicle having left and right lower rear brake lights and a center high-mounted stop lamp (CHMSL) flashes the CHMSL when brakes are initially applied. The lower brake lights do not automatically flash. After a predetermined duration, the CHMSL remains continuously activated until brakes are removed. A semiconductor oscillator circuit is configured to be energized when brakes are applied. It produces an oscillating signal which is responsible for causing the CHMSL to flash. A semiconductor timer circuit is also configured to be energized when brakes are applied. It produces a time out signal which activates a predetermined duration after brakes are applied and which is responsible for causing the CHMSL to remain continuously activated. The outputs of the oscillator and timer circuits are combined at a semiconductor switch which drives the CHMSL.
