Abstract: An automatic vehicle brake light flashing system for identifying an extremity of a vehicle braking force includes a plurality of brake lights connected to a G-force meter. A power supply source transmits a brake power signal to the G-force meter only when the brake switch is activated during vehicle braking procedures. The G-force meter determines a G-force value inside the vehicle only upon receiving the brake power signal. A processor generates and transmits corresponding brake light signals to the brake lights so that the brake lights are caused to flash at different frequencies upon automatically receiving the corresponding brake light signals. Such frequencies may include: fast flashing brake lights for hand force braking/sudden stopping; moderately slow flashing brake light for medium force braking; regular solid brake light for light braking; and contestant emergency warning flashing lights for front and rear end collisions.
