Abstract
A method for obtaining a luminous device the turned-on aspect of which is different from the turned-off aspect, the device including a mask that is able to be partially passed through by light, one or more light sources, and a closing outer lens that is placed downstream of the mask. The one or more light sources and the mask are arranged with respect to one another so that the mask directly or indirectly receives the light rays emitted by the one or more light sources and so that only some of these emitted light rays pass through the mask. The method includes a step of arranging the one or more light sources in the luminous device in number and in power so that the light rays exiting from the luminous device form a signalling light beam.
