EXTERIOR REARVIEW MIRROR WITH CONSTANT GROUND ILLUMINATION

A method for assembling an exterior rearview mirror assembly includes providing a mirror head and a mounting base and pivotally attaching the mirror head at the mounting base. An illumination device is provided that includes a base portion and a movable portion movably disposed at the base portion, with the movable portion including a light source. The base portion is fixedly disposed at the mirror head. The assembled mirror assembly is configured so that, with the mounting base attached at the side of the vehicle, and when a powerfold actuator pivots the mirror head, and with the light source operated to emit visible light, the movable portion moves relative to the base portion as the mirror head pivots so that light emitted by the light source is directed toward the same ground area at the side of the vehicle throughout the range of pivotal movement of the mirror head.
