Abstract
A fog lamp is provided with a light source bulb having a filament as a light source for emitting light, and a secondary light source formed by reflection and collection of the light from the filament; and a reflector having a reflection surface that irradiates the light from the light source bulb forward. The reflection surface of the reflector is constructed so as to irradiate the light from the secondary light source downward of the predetermined cut-off line.
