Abstract
A vehicle equipped is with a light-emitting apparatus 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. The light transmitting tube has a tubular cladding, a core situated inside the tubular cladding and formed of a material having a refractive index higher than that of the tubular cladding, and a belt-like reflective layer formed between the tubular cladding and the core. The light transmitting tube is an extrusion molded product integrally and simultaneously formed by the tubular cladding, core and reflective layer. 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.
