The present invention relates to a lighting and/or signaling device 1 for motor vehicles, comprising: - at least one light guide 2 having a light extraction surface 21 and a light emission surface 22; - at least a first 11 and a second 12 light source which are structured so as to emit light when supplied with electric energy.The first light source 11 faces a first light inlet surface 31 of the light guide so that the light emitted by the first light source penetrates the light guide through the first light inlet surface and then propagates with a first propagation orientation O1 inside the light guide while keeping the condition of total internal reflection between the light emission and light extraction surfaces. The second light source 12 faces a second light inlet surface 32 of the light guide so that the light emitted by the second light source penetrates the light guide through the second light inlet surface and then propagates with a second propagation orientation O2 inside the light guide while keeping the condition of total internal reflection between the light emission and light extraction surfaces.The light extraction surface comprises: - at least a first plurality of light extractors 41, each of which is configured to extract, from the light guide, only light having said first propagation orientation O1, and - at least a second plurality of light extractors 42, each of which is configured to extract, from the light guide, only light having the second propagation orientation O2. The aforesaid at least two light sources are configured to be switched on independently of each other. The lighting and/or signaling device 1 comprises a control unit 50 configured to control the first and second light sources independently of each other according to predetermined switch-on sequences so as to generate an animated lighting effect on said light emission surface.
