An exterior rear view mirror assembly is disclosed which incorporates a warning
light actuatable in conjunction with the vehicle turn signals to alert adjacent
motor vehicles of an anticipated turn. The warning light is integrated into a first
decorative cover member and may be connected to the vehicle turn signal circuit
by way of connectable electrical leads or by an integrally formed plug and outlet
arrangement. A second decorative cover member may be substituted for the first
decorative cover member when it is not desired to incorporate the warning light.
