Abstract

A lighted exterior mirror assembly configured for attachment to a side of a vehicle includes a reflectance element that is movably positionable by the driver of the vehicle to adjust its rearward field of view when the lighted exterior rearview mirror assembly is attached to the side of the vehicle, and a unitary light module having at least one light source. When the mirror assembly is attached to the side of the vehicle and when the light source is electrically powered, light emitted by the light source illuminates a ground area adjacent the vehicle of at least approximately 2 feet by 4 feet. When the mirror assembly is attached to the side of the vehicle and when the light source is electrically powered, light emitted by the light source provides a ground surface illumination intensity at the illuminated ground area of at least approximately 5 lux.
