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.
Claims20
A traffic signal alert apparatus for monitoring the condition of an existing traffic signal light from a non-direct viewing location, comprising:
- a) said existing traffic signal light having a housing with a front side, a first side, a second side, a rear side, a top side and a bottom side, said existing traffic signal light further having a go light, a caution light and a stop light positioned on said front side of said existing traffic signal light housing;
- b) a first light transmissive rod having a first distal end positioned to face a selected one of a go light, a caution light and a stop light, said first light transmissive rod extending to a second angled end;
- c) a second light transmissive rod having a third angled end secured to the second angled end of the first light transmissive rod, forming a substantially right angled connection there-between, said second light transmissive rod having a fourth distal end positioned for remote viewing from one of said first side and said second side of said existing traffic signal light;
- d) said traffic signal alert apparatus secured to said existing traffic signal light housing;
- and
- e) wherein the first distal end and the second angled end of the first light transmissive rod and the third angled end and the fourth distal end of the second light transmissive rod are treated to ensure transmission of light through the first and second light transmissive rods.
