ABSTRACT:
A vehicular variable brake light intensity system including at least one light situated on a vehicle. Also included is a brake pedal potentiometer with a pair of contacts. The resistivity between the contacts is adapted to change as function of the motion of the brake arm during braking. Control circuitry is adapted to allow the brake lights to emit light with an intensity which is a function of the amount of deceleration in a first mode of operation. Also, in a second mode of operation, the control circuitry is adapted to actuate the light intermittently upon the deceleration surpassing a predetermined amount.
