Even a traffic light in my little world would work differently. In my little world there would be four coloured lights on a traffic light signal. "Red" to stop and wait, "Amber/orange" to prepare for a change, "green" to go and "Blue" for dormant signals. The blue light is the same as green but it is warning you that the other lanes in the junction are not being controlled so be cautious. The blue lights would come on at about 1 in the morning when there are very few cars on the road. The amber light would not sit under the red light but would be a bar on the side of the red and green lights that shrinks or grows to show the driver how long he has before the lights change, it would be like a countdown timer that takes about 7 seconds to expand or retract.
The pedestrian crossing lights would also be totally different, they would just be a heads up sign and would not resemble a traffic light until a pedestrian presses the button to cross. When they press the button the text disappears and the green light shows with the orange bar on the side expanding upwards, when the orange bar has fully expanded the green light turns off and red light turns on. Then the orange light shrinks again, when it reaches the bottom the red light turns off and green light turns on. Then the green light shrinks and the heads up text returns to the screen.
