ABSTRACT:
A plurality of lighting units using light emitting diodes as light sources is accommodated in a lamp housing in such a state as to be supported on a common metallic support member provided tiltably. When a part or all of the lighting units are turned on, the light emitting diodes generate heat with a light emission. These light emitting diodes are supported on the common metallic support member. Also in the case in which any of the lighting units is turned on, therefore, the heat generated by the light emitting diodes is moved to the metallic support member having a large heat capacity through boards and light source support blocks by a heat conducting function. Consequently, a rise in the temperatures of the light emitting diodes can be suppressed.
