[origin: EP1643188A1] The light source (11) consisting of a diode chip is supported on a high heat conducting heat sink (14) which connects to a more massive heat sink (17) by convection (15) or a fan (19) in a housing (16) formed from the vehicle body. A lens (18) concentrates and directs the light rays.
