Abstract: A motor vehicle signaling device light module includes a substrate on which a matrix arrangement of elementary light sources is mounted, a connector fixed to the substrate having a rectangular footprint with a long side and a narrow side, and a support designed to hold the substrate in position in the signaling device. The substrate is curved around an axis of curvature, and the light sources are arranged to produce a convex display from the point of view of a user outside of the vehicle, so that the long side of the connector is substantially parallel to the axis of curvature.
