Abstract
A lighting and/or signaling device and method comprising an opaque element that can move between at least two positions, one of the positions interposing the opaque element between the main light source and the optical focusing device, in which the opaque element is arranged so that when it is interposed between the main light source and the optical focusing device it prevents rays originating from outside the lighting and/or signaling device from being focused, especially in a line or spot, by the optical focusing device, in order to prevent degradation of the lighting and/or signaling device.
