What happens to light when it passes through a red filter?
After pure, white light passes through a red filter, all the other colors in the spectrum will flow out of the other side. My mistake, I had a faulty source. A red light filter will cause the image to appear as different shades of red. Since it is a red filter only red light can pass through. So you finish up with red light. Whether it is focussed to an image or not is of no consequence. As to different shades of red, you will get the shade of red that is passed by the filter.

How does a trafffic light work?
A traffic light is placed at an intersection of two or more roadways. Each approach of the intersection has at least one signal head with three bulbs (red, yellow, and green) facing it. Cars approaching the intersection can go through it if the light facing them is green and cannot go through it when the light is red. Signals go from green to yellow (to slow down for the red) to red and then back to green. Only one of the two roads at a signalized intersection can have a green light at one time and the traffic on the other road must wait for the light facing them to turn green.
