In an item of luggage includes at least six side walls. The side walls each have at least one outer surface and one inner surface, the outer and the inner surface are substantially parallel to each other. At at least one of the side walls, at least one elevation is provided on the associated outer surface, which elevation includes at least one exit surface that at least partially is not parallel to the outer surface of the respective side wall, and at least the side wall which includes the at least one elevation is made from a plastic material that contains a fluorescent dye and is light-conducting and light-transmissive such that light is adapted to be introduced into the respective side wall and transmitted and exit at the respective at least one exit surface. A conversion of invisible UV light into visible light takes place in the respective side wall.
