A programmable multi colored Light Emitting Diods (LEDs) rectangular display (panel) to replace the conventional traffic lights, the conventional traffic lights are generally vertically arranged consumes relatively alot of power and embedded into a bulky housing, the red light on top of the yellow light and the yellow light on top of the green light, the red light represents traffic must stop at an intersection, yellow light represents caution and green light represents traffic may pass, while in the new embodiment of the present invention a single rectangular LED display will provide the three traffic signal lights on the same area of the display consecutively,one after the other, in order to achieve this goal, the shapes of the three signal lights and the shapes of the arrow signal lights must be easily distinguishable for the color blind drivers.
Therefore the new invention provides a method and a system of updating the conventional traffic lights to have a less bulky, less power consumption and less expensive programmable LED traffic light display.
