Abstract

A vehicle brake light system including a brake light circuit containing a circuit element connected to brake pedal position sensing means so that the brightness of the brake lights or the number of brake lights illuminated depends upon how far the brake pedal is depressed.

Claims

1. A brake light system for a vehicle having a brake system comprising a brake activation means depressible from a fully non-depressed position to a fully depressed position, the brake activation means progressively increasing braking force as the brake activation means is depressed toward the fully depressed position and progressively decreasing braking force as the brake activation means is returned to the fully non-depressed position, the brake activation means being biased toward the fully non-depressed position with biasing means, said brake light system comprising:

a brake light circuit comprising a brake light source, an electric power source and a voltage regulating means, said voltage regulating means being operationally connected to said brake activation means such that movement of said brake pedal toward said depressed position causes said voltage regulating means to progressively increase the voltage across said brake light source from a certain pre-set level and such that movement of said brake pedal toward said non-depressed position causes said voltage regulating means to progressively decrease the voltage across said brake light source to a limit of substantially no voltage.

2. The brake light system of claim 1, wherein said voltage regulating means comprises a rheostat.

3. The brake light system of claim 1, wherein said brake activation means comprises a brake pedal mounted to the vehicle to be progressively movable relative to the remainder of the vehicle between the fully depressed position and the fully non-depressed position.

4. The brake light system of claim 1, wherein said biasing means comprises a coil spring.

5. A vehicle brake system, comprising:

a brake system comprising a brake activation means depressible from a fully non-depressed position to a fully depressed position, said brake activation means progressively increasing braking force as said brake activation means is depressed toward the fully depressed position and progressively decreasing braking force as said brake activation means is returned to the fully non-depressed position, said brake activation means being biased toward the fully non-depressed position with biasing means;

and a brake light system comprising a brake light circuit comprising a brake light source, an electric power source and a voltage regulating means, said voltage regulating means being operationally connected to said brake activation means such that movement of said brake pedal toward said depressed position causes said voltage regulating means to progressively increase the voltage across said brake light source and such that movement of said brake pedal toward said non-depressed position causes said voltage regulating means to progressively decrease the voltage across said brake light source.

6. The brake light system of claim 5, wherein said brake activation means comprises a brake pedal mounted to the vehicle to be progressively movable relative to the remainder of the vehicle between the fully depressed position and the fully non-depressed position.

7. The brake light system of claim 5, wherein said voltage regulating means comprises a rheostat.

8. The brake light system of claim 5, wherein said biasing means comprises a coil spring.

9. A vehicle having wheels and vehicle drive means, the vehicle comprising:

braking means for slowing the speed of a vehicle, said braking means comprising a brake light circuit including a brake light source, an electric power source and a voltage regulating means and circuit wiring electrically interconnecting said brake light source, said electric power source and said voltage regulating means, such that said voltage regulating means regulates the magnitude of voltage across said brake light source produced by said electric power source and thus regulates the brightness with which said brake light source shines;

rate indicating means indicating the rate of slowing of the vehicle caused by operation of said braking means, said rate indicating means being operationally connected to said voltage regulating means such that said voltage regulating means delivers progressively increased voltage to said brake light source as the rate of slowing of the vehicle increases and delivers progressively decreasing voltage to said brake light source as the rate of slowing of the vehicle decreases.

10. The brake light system of claim 9, wherein said voltage regulating means comprises a rheostat.
