Sand Glass LED Traffic Lights by Thanva Tivawong
Several years ago when I visited Estonia, I really liked their Traffic Lights because they had these electronic LED timers showing exactly how much time was left for the lights to change.
Now Thanva Tivawong takes it into another level by introducing even more intuitive and visually appealing hourglass-inspired design.

Would you replace the current classical stoplights with these new Sand Glass Traffic Lights?
