PURPOSE: To variably change the irradiating direction of a headlight using a concentrative light source without bending an optical fiber cable.
CONSTITUTION: A lighting fixture is composed of a light conductive body 20 to determine a light distribution shape of the irradiating light when the emitting light from an optical fiber cable 10 is made incident and lens bodies 30 and 40 to form desired light distribution on the basis of a light flux incident from this light conductive body 20. A shape of an emitting surface 22 of the light conductive body 20 is formed in a convex shape, and a shape of incident surfaces 31a and 41a of the lens bodies 30 and 40 is formed in a concave shape opposed to the convex shape of the emitting surface 22 of the light conductive body 20, and the lens bodies 30 and 40 are made rotatable.
