Abstract
An illuminator formed from an optically transmissive body which is characterized by internal reflection and which has formed at discrete locations along its length one or more recesses. Each of these recesses includes two opposing surfaces which depend angularly inward from the body to define an included angle therebetween. This illuminator may be used in conjunction with a panel formed with discrete locations of transparency which are positioned contiguous to one or more of the recesses to insure that light passing out from the illuminator will be directed through the transparent location of the panel.
