Abstract: A plurality of horizontally extending rows of alternately green and red signal lights are provided in a signal display grid in each of two respective traffic signal devices. Each traffic signal device includes a STOP-GO indicator and a street indicator positioned respectively at the top and the bottom of the grid. To the left and right of the grid in each traffic device are respectively positioned red and green vertical strip indicators. Stepping switch control circuitry actuates the aforementioned lighting elements such that the red and green lighting elements in the horizontally extending rows are alternately successively actuated to provide a traffic signal display consisting of a block of lighting elements moving in a downward direction within the grid. The STOP indicator and the red left vertical strip indicator are continuously lit during a "red-light" condition; and the GO indicator and the right vertical strip are continuously lit during a "green-light" condition.

Abstract: A traffic signal device, capable of being suspended from an overhead support, includes red colored and green colored lamps secured to an endless conveyor mounted about a pair of spaced sprocket wheels so as to effect movement of the lamps from the top to the bottom sprocket in the facing direction. The lamps are spaced on the conveyor so as to be sequentially exposed through an opening of a casing within which the sprockets and conveyor are mounted. Lighted amber traffic lamps are fixedly disposed at the top and bottom of the opening, and the red and green lamps are switched on and remain lighted only while moving downwardly. Stop and Go signs are likewise switched on and remain lighted while the respective red and green lamps are lighted. The motorist may therefore readily observe the time remaining for a llight change from green to red and from red to green.
