All new traffic light are equipped with LED. I've saw two type of them:
1 eye - only changes the color from red through yellow to green.
It seems to be three groups of color LED's inside of one eye.
And three independed eyes ;-) Each for every color.

It is as incredible as it visible in comparison with usual lamps
especially in sunny day. And furthermore - those traffic units don't
use shadow cover - they shining very bright against the sun ;-)

And one more - it is very easy to implement arrows and other signs
without additional lamp - just show different picture on the same
projector.
