Abstract

A vehicular exterior rearview mirror system suitable for use on a vehicle includes an exterior mirror assembly adapted for mounting to a side of a vehicle and a turn signal light assembly. The mirror assembly includes a reflectance element that is moveably mounted on an actuator for providing remote positioning of the reflectance element. The light assembly is fixedly mounted in the mirror assembly separate from the reflectance element whereby movement of the reflectance element is independent of the light assembly. The light assembly comprises a light source, which comprises at least one light emitting diode that preferably emits visible light having a luminous intensity of at least about 500 mcd and a dominant wavelength of at least about 530 nm when operating, at 25 degrees Celsius, at a forward voltage of less than about 5 volts and when passing a forward current of 20 milliamps.
