Abstract

A lighted exterior mirror system includes an exterior mirror assembly having a folding portion and a non-folding portion. A ground illumination light of the exterior mirror assembly is configured to illuminate with white light a ground area adjacent the equipped side of the vehicle at least at a front door region at the side of the vehicle where occupants may enter/exit exit the vehicle. The ground illumination light includes at least one light emitting diode, which is connected in series with a resistor that acts as a voltage divider to reduce an ignition voltage of the equipped vehicle to a reduced voltage, with the resistor having a resistance of less than about 1,500 ohms. The ground illumination light provides ground illumination of at least about one lux illumination intensity at least on the ground area adjacent the front door region at the equipped side of the vehicle.
