A vehicular blind spot indicator mirror includes a transparent glass substrate having a mirror reflector coated onto the substrate. Visible light reflectance by the mirror reflector coated substrate is at least about 40 percent visible light reflectance for visible light incident upon a front side of the mirror reflector coated substrate. A blind spot indicator light display is disposed to the rear of the mirror reflector coated substrate and emits visible light upon a detection by a blind spot detector. Light emitted by the display passes through the transparent glass substrate to be viewed by a viewer viewing from the front side of the substrate. The display is operable, when electrically powered and when operated in the vehicle during day time driving conditions, to exhibit a display luminance of at least about 60 foot lamberts as measured with the display placed behind, and emitting light through, the transparent glass substrate.
