Claim 1

Serially connected cylindrical light conducting rods for propagating light along the axial length of the cylindrical light conducting rods and for reflecting the light laterally outwardly in two directions, comprising a first and a second cylindrical light conducting rod each having a longitudinal axis and each having an outer cylindrical wall, said first cylindrical light conducting rod having a first longitudinal end section with a first flat end wall, said second cylindrical light conducting rod having a second longitudinal end section, said second longitudinal end section having two outer converging flat walls and a second outer flat end wall, said second outer flat end wall having two sides and two ends, said two outer converging flat walls each having an outer terminating end which is coincident with said sides of said second outer flat end wall, said two outer converging flat walls extending to the longitudinal end of said second longitudinal end section, said two converging flat walls converging as said longitudinal end of said second longitudinal end section is approached, said first and second light conducting rods being connected end-to-end to each other at said first flat end wall and said second outer flat end wall in serial and axial alignment, whereby light propagating through said first cylindrical light conducting rod is transmitted to said second cylindrical light conducting rod via said first flat end wall and said second outer flat end wall, while the rest of the light being propagated is partly reflected laterally outwardly in two directions by said two converging outer flat walls and partly transmitted through said two converging outer flat walls into said second cylindrical light conducting rod, the serially connected conducting rods thereby propagating the light axially and reflecting the light laterally outwardly thereof in two directions.
