Abstract
A fog lamp or the like having a lens disposed in front of a reflector and having portions inclined right and left, which lamp makes effective use of light reflected from the reflector and also has reduced regenerative action in an outer end portion of the lens. The reflector has a left reflecting surface area and a right reflecting surface area with a perpendicular surface containing the optical axis of the reflector as the boundary thereof. The left reflecting surface area is formed as a paraboloid of revolution, while the right reflecting surface area is formed as a laterally diffusing curved surface which reflects incident light from the light source in such a manner that the more distant a reflecting point is from the optical axis in the lateral direction, the larger a reflection angle is with respect to the optical axis.
