A time indicating traffic light that includes a vertically-oriented and rectangular-parallelepiped-shaped housing, a circular-shaped "stop" indicator light, a circular-shaped "caution" indicator light, seven rectangular-shaped "go" indicator lights, and a time indicating display. The circular-shaped "stop" indicator light, the circular-shaped "caution" indicator light, and the seven rectangular-shaped "go" indicator lights are disposed in the vertically-oriented and rectangular-parallelepiped-shaped housing. The seven rectangular-shaped "go" indicator lights have a pair of parallel, elongated, spaced-apart, vertically-oriented, and rectangular-shaped "go" indicator lights, and five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights. The five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights extinguish progressively upwardly towards the circular-shaped "caution" indicator light at a predetermined rate determined by a timer while the pair of parallel, elongated, spaced-apart, vertically-oriented, and rectangular-shaped "go" indicator lights remain illuminated when at least one light of the five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights is illuminated. The time indicating display is disposed on the vertically-oriented and rectangular-parallelepiped-shaped housing and provides a visible display of the time of illumination of the seven rectangular-shaped "go" indicator lights, so that an approaching vehicle can determine when the circular-shaped "caution" indicator light will be illuminated by dividing the time of illumination on the time indicating display by the number of lights of the five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights extinguished and thereby prevent sudden acceleration followed by a sudden stop.

[ The invention claimed is:] [1.] A time indicating traffic light, comprising:a) a vertically-oriented and rectangular-parallelepiped-shaped housing;b) a circular-shaped "stop" indicator light disposed in said vertically-oriented and rectangular-parallelepiped-shaped housing;c) a circular-shaped "caution" indicator light disposed in said vertically-oriented and rectangular-parallelepiped-shaped housing below said circular-shaped "stop" indicator light;d) seven rectangular-shaped "go" indicator lights disposed in said vertically-oriented and rectangular-parallelepiped-shaped housing below said circular-shaped "caution" indicator light and having a time of illumination, a pair of parallel, elongated, spaced-apart, vertically-oriented, and rectangular-shaped "go" indicator lights, and five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights disposed between said pair of parallel, elongated, spaced-apart, vertically-oriented, and rectangular-shaped "go" indicator lights of said seven rectangular-shaped "go" indicator lights; said five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights of said seven rectangular-shaped "go" indicator lights extinguishing progressively upwardly towards said circular-shaped "caution" indicator light at a predetermined rate determined by a timer while said pair of parallel, elongated, spaced-apart, vertically-oriented, and rectangular-shaped "go" indicator lights of said seven rectangular-shaped "go" indicator lights remaining illuminated when at least one light of said five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights of said seven rectangular-shaped "go" indicator lights is illuminated; ande) a time indicating display disposed on said vertically-oriented and rectangular-parallelepiped-shaped housing below said seven rectangular-shaped "go" indicator lights and providing a visible display of said time of illumination of said seven rectangular-shaped "go" indicator lights, so that an approaching vehicle can determine when said circular-shaped "caution" indicator light will be illuminated by dividing said time of illumination on said time indicating display by number of lights of said five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights of said seven rectangular-shaped "go" indicator lights extinguished and thereby prevent sudden acceleration followed by a sudden stop while said pair of parallel, elongated, spaced-apart, vertically-oriented, and rectangular-shaped "go" indicator lights of said seven rectangular-shaped "go" indicator lights provide a means of determining when said circular-shaped "caution" indicator light will be illuminated when said time indicating display may not be easily seen such as when the approaching vehicle is at a far distance by providing a visual comparison of light emanating therefrom with light emanating from whatever lights of said five adjacent, slightly vertically spaced-apart, horizontally-oriented, and rectangular-shaped "go" lights of said seven rectangular-shaped "go" indicator lights are illuminated.
