As I have said before the simplest designs are always the cleverest, this is definitely the case with the Eko Stoplight from designer Damjan Stankovic.
The Eko Stoplight is a great design for a traffic light, and as you can see from the photos the traffic light features a built in timer, which is displayed around the light.
The timer counts down, and shows on the traffic light how much time there is left before it changes to green, so you will never have to sit at another traffic light wondering when it was going to change.
Although this is just a concept at the moment, you never know we may end up seeing this feature in traffic lights in the future.
