You can find these nine eyes traffic lights everywhere in Rotterdam. Nine eyes? Thats the nickname for them, they are used by the public transport as busses and trams! Now there are two red lights, so stop! And when the bus or tram can go they light two white lights for the direction that is now free to go! Example: you go to the right, a white light left under corner and a light right upper corner show you the go. Do you have nine eyes traffic lights in your city?
P.S. Sorry for the late post, to busy at work!
