ABSTRACT:
A light pipe is configured to pass light from a selected light source, such as the green, amber or red light on a traffic signal light to the left, right or rear of the traffic signal light to provide a visual indication of the selected traffic signal light from a remote location where the traffic signal light is not directly visible to the police officer monitoring compliance with traffic laws. The light pipe is secured to the traffic signal light housing by any conventional method, and does not interfere with the normal operation of the traffic signal light.
