Abstract: A clad light-conducting fiber comprising a core, a cladding of lower refractive index than the core, fused to the core, and a plurality of spots of inhomogeneity such as bubbles wholly within the core, spaced along the length of the light-conducting fiber. These light-conducting, bubble-containing fibers are used in a decorative structure comprising a light source and a suitably mounted group of light-conducting, bubble-containing fibers wherein the light is transmitted into and thereafter through the group of fibers, showing decorative points of light along the length of the fibers as well as at their ends.
