PURPOSE: To provide a headlight having a different light distribution characteristic, or capable of switching a light distribution color, and having a simple structure. CONSTITUTION: A louver type lens 4 arranged with plural segment lenses 5 connected with two plate lenses 5A, 5B at an angle of 90 into a louver shape is provided on the front side of light sources 2, 3, and the segment lenses 5 are rotatively driven by a switching mechanism 8 simultaneously. The plate lenses 5A, 5B differ from each other in at least the lens step and color. When the rotation position of the segment lenses 5 is switched, the plate lenses 5A, 5B having different lens steps are set on the optical path of the selective light source, the light distribution color and light distribution characteristic of the light radiation can be switched by the color and lens step of the plate lens, and a headlight having an optional light distribution characteristic can be utilized. |
