Abstract

An exterior door handle assembly includes an illumination device and a handle portion movable to open a vehicle door. The illumination device includes at least one illumination source that, when actuated, emits light. The illumination device includes a lighting strip that is disposed at the handle portion, and the lighting strip extends at least partially along a length dimension of the handle portion. When the illumination source is actuated, the lighting strip is illuminated and the illumination is viewable at least partially along the length dimension of the handle portion by a person viewing the handle portion of the exterior door handle assembly from outside of the vehicle door. When the illumination source is not actuated, the lighting strip may not be readily viewable by and discernible to a person viewing the handle portion of the exterior door handle assembly from outside of the vehicle door.
