Abstract
In order to prevent a driver from feeling strange when he looks at a boundary of illumination between a hot illumination zone and flat illumination zone, a light-grading optical member is provided. A headlight for a vehicle includes a fiberoptic cable and a lamp member for forming incident light beams into a desired illumination profile to illuminate portions in front of the vehicle. The lamp member is composed of a light conducting member to define the profile of the illumination by introducing the light beams from the fiberoptic cable, a first lens member for forming the hot illumination zone and a second lens member for forming the flat illumination zone. The optical member or means for refracting a portion of the light beams is formed on a periphery of the first lens member or on a periphery of the light conducting member, whereby a difference in brightness between the hot and flat illumination zones is reduced.
