Abstract
A vehicle lamp includes an amber light bulb covered with a cup-shaped colorless transparent cap, thus emitting an amber light beam. A colorless, transparent, plain lens is employed. Furthermore, the inner surface of the cylindrical portion of the transparent cap is formed into a plurality of side steps, and the inner surface of the front end portion of the transparent cap is shaped into a Fresnel lens, and the outer surface of the front end portion is shaped into a plurality of fisheye lenses, which makes it more difficult to see the amber light bulb. Therefore, the vehicle lamp appears deep and glittering.
