Patent ID: 7871169

Claim:
A signal mirror for a vehicle comprising: a reflective mirror element having a front side and a rear side; said reflective mirror element comprising a mirror reflector coated onto a light-transmitting substrate; wherein visible light reflectance by said reflective mirror element is at least about 40% visible light reflectance for visible light incident upon the front side of said reflective mirror element; wherein said reflective mirror element does not exhibit substantial spectral selectivity in its reflectance of visible light incident upon the front side of said reflective mirror element; a turn signal light display that emits visible light upon actuation of a turn signal by a driver of a vehicle equipped with said reflective mirror element, said turn signal light display disposed to the rear of the rear side of said reflective mirror element and configured so that said light emitted by said turn signal light display passes through said reflective mirror element to be viewed by a viewer viewing from the front of said reflective mirror element and wherein said turn signal light display exhibits, when electrically powered and when operated in the vehicle during day time driving conditions, a display luminance of at least about 60 foot lamberts as measured with said turn signal light display placed behind, and emitting light through, said reflective mirror element; a blind-spot indicator light display that emits visible light upon a detection by a blind-spot detector that is part of a vehicle equipped with said blind-spot indicator light display, said blind-spot indicator light display disposed to the rear of the rear side of said reflective mirror element and configured so that said light emitted by said blind-spot indicator light display passes through said reflective mirror element to be viewed by a viewer viewing from the front of said reflective mirror element and wherein said blind-spot indicator light display exhibits, when electrically powered and when operated in the vehicle during day time driving conditions, a display luminance of at least about 60 foot lamberts as measured with said blind-spot indicator light display placed behind, and emitting light through, said reflective mirror element; wherein said reflective mirror element comprises a vehicular exterior rearview reflective mirror element; wherein said light-transmitting substrate comprises a glass substrate; and wherein said turn signal light display comprises at least one light emitting diode and wherein said blind-spot indicator light display comprises at least one light emitting diode.
