Abstract: A circuit arrangement for the electrical wiring of a light unit of a headlight for a vehicle, having a control unit which is connected to a power supply, the light unit having at least one semiconductor light source and a temperature measurer, wherein the semiconductor light source has a cathode and wherein the temperature measurer has a cathode, and wherein the light unit has an equipotential bonding contact. In the light unit, the cathodes are electrically connected to one another and/or at least one of the cathodes is electrically connected to the equipotential bonding contact in the light unit.

Abstract: A system for controlling the optical scattering of a light beam in a vehicle comprises a light source, a reflector, a lens, and a headlamp controller. The light source is adapted to generate the light beam. The reflector is positioned about the light source to reflect the light beam. The lens is positioned a distance away from the light source and adapted to receive the light beam from the light source and the reflector and to project the light beam from the vehicle. The headlamp controller is operably coupled to a kinematic sensing device that detects motion characteristics of the vehicle and generates a kinematic signals. The headlamp controller is configured to linearly adjust the distance between the light source and the lens in response to the kinematic signals.
