38 having forwardly projecting spaced upper and lower attachment tracks 39 40 protruding therefrom and running longitudinally therealong track 39 includes a triangular cross section having a circular protuberance 42 at its apex sides 43 44 of the triangle of track 39 complement the radially directed walls 32 33 of cutout 30 and protuberance 42 complements the diameter of hollow 27 39 so that the length of cabling 10 39 can be snap fit onto track 39 to secure the same to the mounting strip 35 track 40 is identically formed to receive a second length of cable 10 39 in snap fitting relationship similarly thereon track 35 can be positioned as desired around a swimming pool walkway sign or other structure to be illuminated or accented by lateral fiber optic lighting fasteners 46 may be passed through bores 47 located in axially spaced placements intermediate the tracks 39 40 in order to secure the strip 35 in position the space 48 exposed on front surface 38 between tracks 39 40 after mounting respective cables 10 39 thereon may be made of or coated with a reflective substance to provide the effect of continuous lateral illumination from the top edge 49 to the bottom edge 50 along the strip 35 as with cable 10 one or more light sources 52 are directed axially into one or both ends of each cable 10 39 fig4 illustrates another cable device 10 34 similar to device 10 39 of fig3 but which integrates the functions of core 12 39 and sheath 17 39 in a modified mounting strip 35.
