Abstract: A lighting device for motor-vehicle comprises a reflective element having a plurality of projecting sectors which are equi-angularly spaced from each other, located around a light source arranged at the centre of the reflective element. The projecting sectors have reflective surfaces surrounding the light source which define a theoretical secondary reflective surface which is substantially different from the primary base surface from which the sectors project. The high discontinuity created in the surface of the reflective element by the presence of the projecting sectors gives rise to a unique aesthetical effect visible both in the condition of device on and in the condition of device off, the device is provided with a transparent element which is substantially clear, i.e. with no optical prisms.
