Abstract
A light display is disclosed herein for decorative purposes including a light source emitting light rays through a dichroic filter for removing undesired color and infrared rays followed by introducing the filter rays into a selected, polished end of a light conducting rod or mirrored tube. Selected peripheral areas of the rod or tube are etched or apertured to permit exit of light therethrough at predetermined locations along the length of the rod or tube. The end of the rod or tube opposite from its polished end is provided with a mirror for reflecting light rays back through the rod or tube.
