A lighting system (20, 20') for preferentially illuminating the seating area (38) of a mass-transit vehicle (22) includes a light fixture (42) with a lam p housing (52) longitudinally disposed above the seating area (38). An electrically energized light source (74) is mounted at at least one end of t he light fixture (42). At least one solid-core semi-rigid light pipe (76, 78, 8 0) extends from and is optically coupled to the light source (74). The light pi pe (76, 78, 80) receives light from the light source (74), transmits the light along its length, and emits the light laterally into the passenger compartme nt (24). The light pipe (76, 78, 80) runs parallel to and is suspended from the lamp housing (52) between the lamp housing (52) and the seating area (38) so that the lamp housing (52) can direct laterally emitted light from the pipe (76, 78, 80) into the seating area (38). The light pipe (76, 78, 80) can be supported by a hanger device (92). Additionally, the light source (74) can comprise a dual-port light source (74k). |
