Countdown counters are pretty common for pedestrians, letting them know how much time they have to cross. Drivers could use them too, and might even save a bit of time and energy if they were ready to roll when the light changed. Thanva Tivawong has designed this very clever interpretation of a traffic signal that could only work with LEDs. This is so much better than the tired old designs that have been around forever.
LED lights trickle down to make an obvious statement, regarding the time left for the lights to change. Easy and intuitive.
And very clever. More at Yanko
