led traffic lights

Slowly but surely the Tokyo government continues its devious plot to replace the ineffective standard traffic lights with bright, clear led ones. First is was the main strip of Ginza, and then I noticed that the lights at Furukawabashi Crossing are now led. Even in direct sunlight it's totally obvious which light is lit, and when not lit they are near black. Each color seems to made of concentric circles of perhaps 100 individual leds. I am assuming they are lower power and longer lasting than traditional bulb lights. And such a vibrant green! Really, technology is just so cool.
