Abstract
A lens member for a flat zone illumination of a headlight has a light incident surface which receives light beams introduced from a centralized light source through a fiberoptic cable, a light emitting surface which has a cylindrical lens portion for irradiating the light beams in front of a car and a curved light conducting portion between the surfaces which has total reflecting surfaces on the peripheries thereof. The light emitting surface is formed to slightly incline with respect to a light axis of a hot zone lens member so that the light beams are refracted in parallel with the light beams for the hot zone illumination when they are emitted from the surface and increase the brightness of the flat zone illumination.
