<p>PURPOSE:To realize a vehicular lighting system capable of guiding and/or emitting a large quantity of light with high efficiency while being low-priced. CONSTITUTION:A light transmission hose 2 is formed of cylindrical clad material 4 with flexibility, liquid or flowable core material 5 higher in refractive index than the clad material 4 and filled into the clad material 4, sealing plugs 6, 7 for closing both end opening parts of the clad material 4. A luminous part 3 is formed being provided with light transmissiveness at the whole or/and part of the clad material 4 or/and sealing plug 7.</p> |
