red yellow green
What color are trafic lights from top to bottom?
red, yellow,and Green!
Is there a reason the traffic light has red on top and green on the bottom?
Yes. Red means stop, obviously, and it is on top so you can see it from further away. If you are cresting a hill for example, you can see the top of the traffic light before the bottom which gives you more warning that you need to stop. Traffic lights are all the same to that people who are color blind still know what the light is indicating.
Did traffic lights change. i seem to remember them being green on top and red on the bottom.?
The lights are still in this order: RED YELLOW GREEN
How can the colorblind distinguish between red and green traffic lights?
Despite their obvious placements on top or bottom of a traffic light, traces of orange and blue are added to the red and green lights to aid those with red-green color blindness to distinguish between the two. This only affects red-green color blind people. The order of the colors never change. Someone who is colorblind knows it is red on top, yellow in the middle, and green on the bottom. Blue is added to a green traffic light and orange added to a red traffic light. Next time you are out and about, look at the traffic lights. I know in Miami some green traffic lights have a distinct blue undertone, but not all of them have this same undertone. You can also do an image search on a search engine to see what I am talking about.

Why the red light top of yellow and green?
The first traffic lights had the red on top and green below as a left over of train signals; today lights are setup by a set of standards to ensure that color blind individuals know which light is which without being able to see that actual color.
What is the light on top of traffic lights that cops can turn on?
Emergency vehicles carry a transponder that transmits a radio signal to change the traffic lights to green for them.
Is color blindness deadly?
Color blindness is far from deadly; it is a minor inconvenience. People very seldom find themselves in a situation in which their lives depend upon correctly identifying a color. Of course, we do have to know what color a traffic signal is, however, we know that the red lights are on top, yellow in the middle and green at the bottom, so we can tell by position alone even if we can't identify the actual color.
