    • PROBLEM TO BE SOLVED: To install a sub-light source having a compact form in a limited space inside a lamp chamber, without shielding the light from a main light source.
      SOLUTION: The two main light sources 2 and the three sub-light sources 3 are installed in the lamp chamber of a vehicular headlight 1. The main light sources 2 are used, respectively as a low-beam lamp 2A and a high-beam lamp 2B, and the sub-light sources 3 are used, respectively as a clearance lamp 3A, a turn signal lamp 3B and a running lamp 3C. A surface light-emitting body including an organic EL is used as each sub-light source 3, and is juxtaposed on a light source base which is common to the main light source 2. The surface light emitting body surrounds the main light source 2, generates a diffused light, in an area sided sideways from an optical path of the main light source 2, and illuminates a translucent cover of a lighting fixture front face from an inside thereof.
