A device for supplying and controlling a light source in a half-dipped signaling lamp includes at least one light source (3), housed in a base support, and a cap (4), removably fastened to the support base. At least one window seat (5a, 5b) is made in the cap and an optical prism (6a, 6b) is associated to the window seat. Reflecting means (7) direct a light beam emitted by the light source (3) toward the optical prism (6a, 6b) while sensor means (21) detect the intensity of the light radiation emitted by the light source (3) or of a representative quantity of the light radiation. A supply and control central unit (CC) receives the signals (S1, S2), coming from the sensor means (21) and supplies the light source (3). |
