Abstract

A lighted exterior mirror assembly includes a housing that houses a reflectance element, and includes a turn signal indicator disposed at a portion of the housing. The turn signal indicator is fixedly disposed at the housing separate from the reflectance element whereby movement of the reflectance element is independent of the turn signal indicator. The turn signal indicator comprises a plurality of light emitting diodes arranged in a plane that is generally horizontal when the lighted exterior mirror assembly is attached to the side of the vehicle. The plurality of light emitting diodes may be disposed behind a light-transmitting cover and, when the lighted exterior mirror assembly is attached to the side of the vehicle and when the plurality of light emitting diodes is powered, the plurality of light emitting diodes emits light that is viewable at least rearward of the vehicle.
