Abstract

The exterior handle configuration of the present invention includes a panel having a recess portion and a handle that covers the upper periphery of the recess portion. An inside surface of the handle is finished with a mirror treatment that reflects and diffuses light. At least one light source fixed at the panel emits light that is directed between the recess portion and the handle. A reflecting surface reflects light emitted from the light source to the inside surface of the handle. The handle configuration of the present invention improves the visibility of the exterior handle during nighttime in a visually pleasing manner.
