<P>PROBLEM TO BE SOLVED: To improve an optical output of a waveguide line by reducing a problem of an optical leakage and improve uniformity of an appearance of the waveguide line by preventing formation of hot spots when being switched on. <P>SOLUTION: The vehicle lighting/signaling device is provided with at least one light source and at least one optical waveguide line through which a light beam is transmitted. The optical waveguide line has an incident face, on at least one of end parts, which connects the optical waveguide line with the light source, a first face forming an output face of the light beam and a second face forming a light reflecting face separated from the output face, and the optical waveguide line has at least one curved part and, moreover, at least one corner part, in a region of the curved part, which is projected toward an outside of the curved part and where a bevelled angle is formed with two cut-out faces (S1, S2) for reflecting an incident light to the optical waveguide line. <P>COPYRIGHT: (C)2008,JPO&INPIT |
