The lights are still in this order: RED YELLOW GREEN
The red light on a traffic light is typically located at the top. The sequence of lights from top to bottom is red, yellow, green.
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.
The lowest light on a traffic signal is green. Some cities use traffic lights that are not arranges top to bottom but rather side to side. In this event the green light is usually the furthest to the right.
It is usually on the bottom of the traffic light.
In Quebec, traffic lights have a horizontal configuration with red on the left and green on the right, while in other regions, the vertical configuration is more common with red on top and green on the bottom.
The red light on a vertical traffic signal is usually at the top, followed by the yellow or amber light in the middle, and the green light at the bottom. These lights communicate different signals to drivers to indicate when to stop, prepare to stop, or go.

The green light on the traffic light is on the bottom. The yellow is in middle, the red is on top. However, in some municipalities, the traffic lights are not vertical, they are horizontal. In these instances, the green light is usually, but not always, the furthest to the right.
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.
