Claim 0:
1. A vehicular exterior rearview mirror assembly, the vehicular exterior rearview mirror assembly comprising:
a mirror reflective element sub-assembly comprising a mirror reflective element;
wherein mirror reflective element comprises a glass substrate;
said glass substrate having a first side and a second side separated by a thickness dimension of said glass substrate;
wherein a metallic reflector coating disposed at said glass substrate;
said mirror reflective element sub-assembly comprising a mirror back plate;
wherein said mirror back plate comprises a plate portion having a front plate side facing the second side of said glass substrate and a rear plate side rearward of said front plate side that is separated from said front plate side by a thickness dimension of said plate portion of said mirror back plate;
wherein said mirror back plate comprises first structure at said rear plate side;
wherein said first structure is configured to attach at an actuator of the vehicular exterior rearview mirror assembly;
wherein said mirror back plate comprises second structure at said rear plate side;
wherein said mirror reflective element sub-assembly comprises a heater pad disposed between the second side of said glass substrate and said front plate side of said plate portion of said mirror back plate;
wherein said heater pad is adhered at said second side of said glass substrate, and wherein said front plate side of said mirror back plate is adhered at said heater pad;
wherein said heater pad comprises a light-transmitting portion;
said mirror reflective element sub-assembly comprising an indicator element disposed at said second structure of said mirror back plate, said indicator element having a circuit board and a light source disposed at said circuit board, wherein said light source is activatable to emit light;
wherein said indicator element comprises electrically conducting terminals electrically connected to said circuit board and extending therefrom;
wherein said electrically conducting terminals extending from said circuit board extend into a connector portion of said indicator element forming an electrical connector configured for connection to another electrical connector for electrically connecting circuitry of said circuit board at least to electrical power when the vehicular exterior rearview mirror assembly utilizing said mirror reflective element sub-assembly is mounted at a side of a vehicle equipped with the vehicular exterior rearview mirror assembly;
wherein said indicator element comprises a diffuser that diffuses light emitted by said light source;
wherein said indicator element is a self-contained unit;
wherein an icon is established through said metallic reflector coating disposed at said glass substrate;
wherein said icon of said indicator element is associated with a blind spot detection system of the equipped vehicle;
wherein said icon comprises a light-transmitting aperture;
wherein, when said light source is activated and with the vehicular exterior rearview mirror assembly attached at the equipped vehicle, light emitted by said light source passes through said light-transmitting portion of said heater pad and through said light-transmitting aperture of said icon;
wherein, with the vehicular exterior rearview mirror assembly attached at the equipped vehicle and when said light source is activated, said icon is illuminated and is viewable by a driver of the equipped vehicle; and
wherein said icon, when said light source is activated, has a luminance of at least 5,000 candelas/square meter as viewed along its axis of highest brightness and has a luminance of less than 30,000 candelas/square meter as viewed along its axis of highest brightness.
