A mirror reflective element sub-assembly for an exterior rearview mirror assembly of a vehicle includes a mirror reflective element, a heater pad, a mirror back plate, and a blind spot indicator module attached at a rear side of the back plate. The heater pad is adhered at the rear of the reflective element with a light transmitting aperture of the heater pad juxtaposed with a light transmitting aperture of the mirror reflector of the reflective element. The heater pad is adhered at the mirror back plate with its light transmitting aperture juxtaposed with a light transmitting aperture of the mirror back plate. Light emitted by the blind spot indicator module passes through a light-transmitting aperture of the mirror reflector to provide an illuminated icon to a driver of the vehicle when a blind spot detection system of the vehicle detects the presence of another vehicle in an adjacent lane.
