A lighting module (5) for vehicles includes a light source (6), a reflector (7) and an actuator (8) to rotate the reflector relative to the light source around a first axis (A); wherein the reflectorforms, together with a lens (9) assembled angularly rigid therewith, a rotating unit (10) powered by the actuator and the light source, the actuator and the rotating optical unit are operatively associated with a framed support (11) formed by a rigid metallic structure; the rotating optical unit (10) is supported in idly manner solely by a bottom portion (14) of the framed support (11) as a firstsub-assembly (15) completely independent of an upper portion (16) of the framed support (11) bearing the light source (6), which forms, with a printed circuit board (12) and electronic components (13), a second sub-assembly (18) supported solely by the upper portion (16) of the framed support (11), the first sub-assembly (15) being mechanically disconnected in rotation from the second sub-assembly(18).
