Abstract: PROBLEM TO BE SOLVED: To allow a pair of right and left fog lamps placed at the front end of a vehicle to have sufficient performance in distributing light as such if their reflectors are made of a resin and have reflecting surfaces asymmetrical with respect to their optical axes. SOLUTION: Of a plurality of lens steps formed on the portions of lens surfaces which are located in front of reflecting surfaces 18, lens steps 54A for forming hot zones are not formed at the same position (relative positions obtained through parallel translation) on right and left fog lamps 10R, 10L, but are formed ahead of a reflecting surface area (area with a larger projected area along the direction of an optical axis) inside its optical axis Ax along the direction of vehicle width, respectively. In that case, the lens steps are formed in symmetrical relative positions, each in front of a position that is on the side of the optical axis Ax and is approximately halfway between the optical axis Ax and the outer periphery of the reflecting surface 18, while avoiding some of projections molded integrally with the back of a reflector.  Therefore, by means of light reflected from positions appropriate for hot zone formation, the hot zones can be formed in positions on the reflecting surfaces 18 where surface accuracy is excellent with no recesses formed.
