Wireless transmission of the color in traffic lights.

It would be good thing if traffic light will transmit wirelessly their own situation, if the traffic light is red or green, and in how long it is going to be changed, it will be good for smart cars that would know whether to slow down before the stop light or not, and it would be also good if we have traffic lights after a curve and we are not always able to see them and we always slow down,so if we will know this we will use the right speed.
A smartphone app you can also get the data.
