The invention relates to a lighting module and / or signaling device for a motor vehicle in particular, comprising means of optical deviation (20) of light rays emitted by a first light source (22). A frame (18) has two screens (28, 30) and a base (32) which connects transversely one of their ends. The frame is rotatably mounted about an axis (14) under the effect of an actuator (12) so that said two screens are able to take a position on the path of the light rays deflected by said optical deviation. At least one structural element (60), distinct from the base, extends between the screens.
