The invention includes a lighting device with a signaling module that can move in at least a first direction and a lighting module that can move in a second direction different from the first direction. The movable lighting module being able to take a position that is invisible and a position that is visible from outside the lighting device. The lighting device further including a controller designed to control a movement of the lighting module such that: in a first mode, called daytime mode, the lighting module assumes the invisible position; in a second mode, called nighttime mode, the lighting module assumes the visible position. The controller moves of the signaling module such that at least one part of the signaling module moves in the first direction in order to authorize a movement of the lighting module in the second direction from the invisible position to the visible position.
