Exterior mirror reflective element sub-assembly

摘要

A mirror reflective element sub-assembly includes a mirror reflective element and a mirror back plate. The back plate has an indicator mounting portion. An aperture is established through the back plate generally at the indicator mounting portion. A heater pad is disposed between the mirror reflective element and the back plate. The heater pad has a light transmitting portion generally aligned with the aperture of the back plate. A self-contained substantially sealed indicator is mounted at the indicator mounting portion and has a light source that is activatable to emit light. When an equipped exterior rearview mirror assembly is mounted at a side of a vehicle and with the light source activated, light emitted by the light source transmits through the aperture of the back plate and the light transmitting portion of the heater pad and exits the mirror reflective element.
