Abstract

A lighted exterior mirror system includes an exterior mirror assembly having a folding portion and a non-folding portion. The non-folding portion is configured to mount to a side of a vehicle and the folding portion includes a reflective element. The folding portion is movable relative to the non-folding portion and between a normal operating position and a folded position. A ground illumination light is configured to project a pattern of light from the exterior mirror assembly to provide a lighted zone on a ground area adjacent the side of the vehicle at least at a front door region at the side of the vehicle where occupants may enter/exit the vehicle. The pattern of light projected by the ground illumination light provides ground illumination of at least about one lux illumination intensity at least on the ground area adjacent the front door region at the side of the vehicle.
