ABSTRACT:
A three-dimensional sign, which may include an angularly disposed perimeter with a mirror-like surface, for reflecting light from the headlights of oncoming vehicles so as to gather light on the sign and make the symbols or letters and background stand out and become easily visable at night. An illusion is created by placing a total accentuated subject or message in a bed of scotch-like retro-reflecting background. Contrasting colors or contrasting density, such as black to white, are provided as well as a border on the figure or numerals of the sign to accentuate the message thereof. This is particularly so if the border is made at least partially of retro-reflective material. The angularly disposed mirror-like perimeter enhances the light on the sign through additional collection of light and redirecting it to the internal retroreflecting and fluorescent materials.
In some situations, the reflective angular border may be eliminated and contrasting symbols, figures etc. may be made more visible in either daylight or by headlights at night by being surrounded by mirror-like strips which, in turn, are surrounded by border strips of contrasting density. The background may be of translucent plastic material.
