Abstract
An apparatus and method, according to an exemplary aspect of the present disclosure includes, among other things, a transparent lighting source, a switchable opaque film bonded to the transparent lighting source to provide a vehicle component, and an electrical connection that connects to the transparent lighting source and the switchable opaque film such that the switchable opaque film is electrically controlled to switch between an opaque state and a transparent state. A control unit independently controls the switchable opaque film and the transparent lighting source based on a predetermined application for the vehicle component.
