Abstract

210,528. Robinson, J. Nov. 1, 1922. Drawings to Specification. Lighting, systems of; lantern shutters. - The light emitted by vehicle lamps may be polarized, as by means of a number of reflecting surfaces, or it may be made intermittent by means of an alternating current supply or by an automatically operated switch in the lighting circuit, or by a rotated sector-shaped shutter.
