1. A mirror reflective element sub-assembly suitable for use in an exterior rearview mirror assembly of a vehicle, said mirror reflective element sub-assembly comprising:

  • a mirror reflective element;

    said mirror reflective element comprising a transparent glass substrate with a mirror reflector disposed at a surface thereof;

    a mirror back plate comprising a plastic molding formed in a plastic injection molding operation;

    said mirror back plate comprising a first side and a second side;

    said mirror back plate comprising a mirror actuator attaching portion that is established at said first side by said plastic injection molding operation;

    wherein said mirror actuator attaching portion comprises structure for attaching said mirror back plate to a mirror actuator of an exterior rearview mirror assembly, and wherein said mirror actuator comprises an electrically operable mirror actuator;

    wherein said mirror back plate comprises an aperture;

    a heater pad disposed between said mirror reflective element and said second side of said mirror back plate;

    wherein said heater pad has a light transmitting portion that is generally aligned with said aperture of said mirror back plate;

    wherein said mirror reflector comprises a light-transmitting portion thereof that is generally aligned with said light transmitting portion of said heater pad;

    an indicator module comprising a housing;

    a circuit board disposed in said housing and wherein said circuit board comprises at least one light emitting diode activatable to emit light;

    wherein said circuit board is oriented in said housing so that said at least one light emitting diode faces towards said mirror reflective element;

    wherein said indicator module is associated with a blind spot detection system of a vehicle equipped with an exterior rearview mirror assembly equipped with said mirror reflective element sub-assembly;

    said indicator module comprising a passageway that (i) is angled relative to said mirror reflective element and (ii) is canted toward a side of the equipped vehicle at which the exterior rearview mirror assembly equipped with said mirror reflective element sub-assembly is mounted; and

    wherein, when the exterior rearview mirror assembly equipped with said mirror reflective element sub-assembly is mounted at the side of the equipped vehicle and with said at least one light emitting diode activated, light emitted by said at least one light emitting diode passes through a light diffuser and through said light transmitting portion of said heater pad and through said light-transmitting portion of said mirror reflector and exits said mirror reflective element to provide a visual icon visible to a driver of the equipped vehicle who is driving the equipped vehicle and who is viewing said mirror reflective element.
