This is a typical Dutch traffic light you encounter near buslanes, and intersections. I made this model for a time management function. As you can see in the pictures a fully functional traffic light.

When the RED light is lit you may not interput that person. When RED and Orange are lit, it will take an X amount of time before he is availible. When GREEN is lit the person is availible
