Abstract: A plurality of light units are connected to a common electrical conductor, spaced apart along a length of the conductor. Each light unit includes an enclosure comprising a housing containing a light emitting diode therein and a cap fitting over an open end of the housing. A plurality of optical fibers bundled together at one end extend through an opening in the cap, with the bundled ends arranged substantially evenly and proximate to the light emitting diode to receive light therefrom. The other ends of the optical fibers are dispersed, and light received from the light emitting diode is emitted from such dispersed other ends.
