Abstract

291,194. Miller, R. A. April 9, 1927. Vehicle lamps; lighting, systems of. - In a vehicle lamp in which an auxiliary source of light f within a reflector e is arranged eccentrically within the main reflector, a second auxiliary source of light within a reflector g is arranged on the exterior of the lamp casing so as to project a beam of light downwardly and to one side. The reflector e preferably is disposed at an inclination above and to one side of the main source of light d so as to project a beam of light downwardly and inwardly with respect to the vehicle, and the reflector g preferably is disposed to one side of the vertical plane containing the axis of the lamp casing so as to project a beam of light outwardly with respect to the vehicle Switch means may be provided so that the main source of light is extinguished when the auxiliary sources are illuminated.
