There are have been great strides in making the the world more green and here goes another one. The solar powered traffic light designed by Cheng-Tsung Feng, Yao-Chieh Lin  and Bo-Jin Wang, who won the 2009 Lite-On Award (Silver Level). This new and innovative traffic light is an attempt to make the infrastructure of the city more sustainable. The light uses Discolor LED (Light Emitting Diode) technology. This technology integrated into the light, allows one light to take the place of the traditional three light system. The single light changes to green, amber and red. By using LEDs, which have become more common in traffic lights, the lights use less energy and by condensing three lights down to one the energy use is further reduced. The design in general is quite ingenious by incorporating the solar panels as a hood.
