Abstract:
A vehicle equipped with a light-emitting apparatus on a running board at an underside of an entrance thereof, wherein the light-emitting apparatus has a light transmitting tube which emits light from its circumferential surface, and a light source which is installed at one end of the light transmitting tube, said light transmitting tube having a tubular cladding made of a (meth-)acrylic polymer, a core situated inside the tubular cladding and formed of a material having a refractive index higher than that of the tubular cladding, said core being made of polystyrene, polycarbonate, styrene-(meth)acrylic copolymer or polymethyl (meth-)acrylate, and a belt-like reflective layer formed between the tubular cladding and the core and extending in a longitudinal direction of the tubular cladding, said reflective layer being made of a (meth-)acrylic polymer including a white pigment or a light scattering material, said light transmitting tube being an extrusion molded product integrally and simultaneously formed by the tubular cladding, core and reflective layer so that a light passing through the core is reflected and scattered by the reflective layer and emitted from an outer surface area opposite to the reflective layer of the tubular cladding.
