PROBLEM TO BE SOLVED: To prevent emission of light other than yellow surely without impairing good appearance and designability, and to improve a commercial value as a fog lamp.SOLUTION: In a fog lamp 1, in a lamp chamber 6 demarcated by a reflector 3 and an outer lens 5, a yellow inner lens 7 is disposed being separated to a light source 2 side from the outer lens 5. Then, in white light L1 and L11 emitted from the light source 2, only a wavelength region of a yellow component in the wavelength region is transmitted as yellow light L3 and L31 by the inner lens 7. Also, the light is made to transmit an optical multilayer film 4 on an inner surface of the outer lens 5. Thus, even when a wavelength region other than the yellow component is mixed in the yellow light L3 and L31 by any chance, it is completely removed. Thereby, emission of light other than yellow can be surely prevented. |
