Abstract: A lighted display device comprises a display panel having a plurality of lighting elements arranged in a pattern, one end of each of a plurality of light conducting fibers are removably received within lighting element locations on the display panel. The other ends of the fibers are received and retained within a support member. A light source is provided for illuminating the other end of the fibers, light from the light source being received by the other ends of the fibers and being conducted to the one ends of the fibers for illumination of the display panel. A movable disk is interposed between the light source and the other ends of the fibers for periodically altering the light received by the fibers to alter the light conducted to the display panel. A sleeve member engages each of the fibers for establishing a predetermined relationship between the portions of the fibers extending between the ends thereof to facilitate untangling of the fibers which become tangled and to prevent tangling of the fibers.
