A signal mirror system for a vehicle includes a reflective mirror element comprising a semitransparent nondichroic mirror reflector coated onto a light-transmitting substrate. The visible light transmission through the reflective mirror element is in the range of from about 1% visible light transmission to about 30% visible light transmission and the visible light reflectance is in the range from 40% visible light reflectance to 80% visible light reflectance for visible light incident upon the front side of the reflective mirror element. The reflective mirror element exhibits substantial non-spectral selectivity in its reflectance. The semitransparent nondichroic reflector comprises a metal thin film layer. A turn signal display, preferably having at least one light emitting diode, is disposed to the rear of the reflective mirror element and configured so it emits light emitted that passes through the semitransparent mirror reflector to be viewed by a viewer viewing from the front of said reflective mirror element with a display luminance of at least about 30 foot lamberts. |
