Solar Traffic Light

via yankodesign.com

Such a simple design. It contains Discolor LEDS which provide Red, Amber, and Green in one piece. My only concern is modern traffic lights are designed for the color blind as well. Red is always on the top or the left. Green is always on the bottom or the right.

If the shape changes based on the status it could work out well. Red octagon for stop, green arrow for go maybe.
