Abstract

PURPOSE:To enable the shaping of an illumination light to any form to heighten the degree of freedom of its design, by composing the illumination light of a light source section, optical fibers for transmitting light from the light source section to a lens system and said lens system for attaining a desired distribution of the light. CONSTITUTION:A light source section 1 is made of a halogen bulb of about 35- 55W and a reflector, for example. Light from the bulb is efficiently introduced into optical fibers 2 through a heat interception filter 3. The light is conducted through the optical fibers 2 to a lens system 4 provided on the front and/or rear of a car body A. The plural optical fibers 2 are bundled depending on the shape and size of an illumination light. The irradiation ports 2'' of the optical fibers 2 are located on the foci of the lens system 4. The lens system 4 comprises condensing lenses 4a and a right and left diffusion lenticular lens 4b in combination, or the like. The irradiation port 2'' of each optical fiber 2 is located on the focus of the lens 4a.
