Abstract

An exterior door handle assembly includes a strap-handle portion pivotally movable to open a vehicle door, a circuit element, a light emitting diode, a light pipe, and an elongated light-transmitting cover. The light emitting diode is disposed proximate an end region of the strap-handle portion and proximate an end region of the light pipe. The strap-handle portion includes structure configured to receive the light emitting diode and the circuit element thereat. The light-transmitting cover is attached to the strap-handle portion and covers the light pipe. The strap-handle portion includes a user input that is actuatable by a person to lock or unlock the vehicle door. When the light emitting diode is electrically powered, light emitted by the light emitting diode passes along the light pipe and passes through the light-transmitting cover so as to be viewable by a person viewing the door handle assembly from outside of the vehicle door.
