Abstract

An equipment part may comprise a carrier, a composite film, and a light source. The composite film may be disposed on the carrier and may form a visible side of the equipment part. The composite film may comprise a light-conducting layer into which the light rays emitted by the light source are coupled. A scatter layer may be disposed on a side of the light-conducting layer facing the carrier, with the light rays coupled into the light-conducting layer emitting through said scatter layer. The composite film may comprise a first and a second paint layer, where the first paint layer may be disposed on a side of the scatter layer facing the carrier, and the second paint layer may be disposed on a side of the light-conducting layer facing away from the carrier. The equipment part may be produced via a method for production of such an equipment part.
