1. An exterior rearview mirror assembly for a vehicle equipped with a blind spot monitoring system, said exterior rearview mirror assembly comprising:

  • a mirror reflective element sub-assembly;

    said mirror reflective element sub-assembly comprising a mirror reflective element;

    said mirror reflective element comprising a mirror glass substrate;

    said mirror glass substrate comprising a surface coated with a metallic mirror reflector;

    wherein said metallic mirror reflector comprises a light transmitting aperture established therethrough, said light transmitting aperture having the form of an icon;

    wherein said icon is established by local removal of said metallic mirror reflector;

    said mirror reflective element sub-assembly comprising a heater pad, wherein said heater pad comprises a light transmitting aperture;

    said mirror reflective element sub-assembly comprising a mirror back plate, wherein said mirror back plate comprises a light transmitting aperture;

    wherein said mirror back plate has a front plate side and a rear plate side spaced from said front plate side by a thickness dimension of said mirror back plate;

    wherein said heater pad is disposed between said mirror glass substrate and said front plate side of said mirror back plate, with said light transmitting aperture of said heater pad juxtaposed with said light transmitting aperture of said metallic mirror reflector of said mirror glass substrate and with said light transmitting aperture of said heater pad juxtaposed with said light transmitting aperture of said mirror back plate;

    said mirror back plate comprising first structure at said rear plate side, wherein said first structure is configured to attach at an electrically-operable actuator that is operable to move said mirror reflective element sub-assembly about two orthogonal axes to allow a driver of a vehicle equipped with said exterior rearview mirror assembly who is viewing said mirror reflective element to adjust his or her rearward view;

    wherein said mirror back plate is formed of a polymeric material by injection molding, and wherein said first structure and said light transmitting aperture of said mirror back plate are formed during injection molding of said mirror back plate;

    wherein said heater pad is adhered to said mirror reflective element at a rear side of said mirror reflective element;

    wherein said front plate side of said mirror back plate is adhered to said heater pad;

    a blind spot indicator comprising a light source that is electrically activatable to emit light;

    wherein said light source comprises at least one light emitting diode having a luminous efficiency of at least 1 lumen per watt;

    wherein said at least one light emitting diode having a luminous efficiency of at least 1 lumen per watt is mounted on a printed circuit board;

    wherein said blind spot indicator comprises a self-contained unit accommodating at least said printed circuit board;

    wherein, with said blind spot indicator disposed at said light transmitting aperture of said mirror back plate, said printed circuit board is orientated so that said at least one light emitting diode having a luminous efficiency of at least 1 lumen per watt faces toward said mirror reflective element;

    wherein said blind spot indicator, when said light source is activated, emits light through said light transmitting aperture of said mirror back plate and through said light transmitting aperture of said heater pad and through said mirror reflective element;

    wherein movement of said mirror backing plate by said actuator moves said blind spot indicator and said mirror reflective element in tandem;

    wherein, when said exterior rearview mirror assembly is attached at a side of the equipped vehicle and when said light source is activated, light emitted by said light source passes through said light transmitting aperture of said metallic mirror reflector, forming an illuminated icon viewable by the driver of the equipped vehicle viewing said mirror reflective element;

    wherein a blind spot monitoring system of the equipped vehicle activates said light source of said blind spot indicator forming said illuminated icon to indicate to the driver of the equipped vehicle presence of another vehicle in a traffic lane adjacent the side of the equipped vehicle at which said exterior rearview mirror assembly is attached; and

    wherein, when said exterior rearview mirror assembly is attached at the side of the equipped vehicle and when said light source is activated, said illuminated icon is present and is viewable by the driver of the equipped vehicle at an outboard region of said mirror reflective element that is outboard relative to the side of the equipped vehicle at which said exterior rearview mirror assembly is attached.
