Patent attributes
A vehicular exterior rearview mirror assembly includes a ground illumination module or turn signal indicator that includes at least one light source operable to emit light when electrically powered. A near field communication device communicates utilizing a near field communication (NFC) standard. Responsive to a near field communication-enabled device being present exterior the vehicle, the near field communication device wirelessly receives a communication from the near field communication-enabled device and determines whether the near field communication-enabled device is an authorized device. Responsive to determining that the near field communication-enabled device is an authorized device, the near field communication device authenticates the near field communication-enabled device as an authorized device for communication with the near field communication device. When the near field communication-enabled device is within a threshold distance to the vehicle, the at least one light source is electrically powered.
