ABSTRACT:
This invention describes the design and method of installation of wild animal highway warning reflectors. The reflector consists of a transparent plate having a flat light entrance surface and a backside reflection surface from which the reflected light is dispersed. The rear surface is comprised of many reflecting toric surfaces arranged vertically and horizontally side-by-side. The new design of the toric surfaces and the unique method of installing the reflectors provide complete reflected light coverage for all variations of roadside terrain to warn wild animals that wish to cross a highway at night. To an animal each reflector glitters with colored light. As a vehicle passes, animals see an unnatural, sequence of lights coming from a plurality of reflectors located along both sides of the highway. Installation of these warning reflectors adjacent to highways where wild animals frequently cross has led to a considerable reduction of the number of accidents.
