Are you bored and bothered when you have to wait for the traffic light to change? Normally, traffic lights have only three colours: red, yellow and green and some traffic lights are so designed with digital countdown.
Thanva Tivawong designed a brand new type of traffic light – sandglass traffic light to entertain bored drivers.
The visual effect of a sandglass makes the waiting time clearer than the common digital countdown system. When the amber light comes on, a 3-2-1 countdown will appear to warn drivers to get ready to stop.
