A traffic light, traffic signal, or stop light is a signalling device positioned at a road intersection, pedestrian crossing, or other location in order to indicate when it is safe to drive, ride, or walk using a universal color code.
Introduction
Traffic lights for normal vehicles or pedestrians always have two main lights, a red light that means stop and a green (or sometimes white for pedestrians) light that means go. Usually, the red light contains some orange in its hue, and the green light contains some blue, to provide some support for people with red-green color blindness. In most countries there is also a yellow (or amber) light, which when on by itself and not flashing means stop if able to do so safely. In some systems, a flashing amber means that a motorist may go ahead with care if the road is clear, giving way to pedestrians and to other road vehicles that may have priority. A flashing red essentially means the same as a regular stop sign. There may be additional lights (usually a green arrow or "filter") to authorize turns. A turn light preceding the opposing through movement is called a leading left turn in the U.S., because it leads the opposing through green light (likewise, in the U.S., a left turn arrow that follows the opposing through movement is known as a "lagging left turn").

@Netrex. Interesting Issues indeed. You can send multiple signals down fiber, using different wavelengths, preventing interference.
