Let make the traffic green. Cheng-Tsung Feng, Yao-Chieh Lin and Bo-Jin Wang have designed a Solar Traffic Light concept. Why is it one light? It is because this traffic light uses Discolor LED (Light Emitting Diode) technology, hosting all the three colors of the lights within a single unit ~ red, amber and green together. While the roofing will be the Solar Panel that powers it. More pictures after the break.
