The method involves emitting a light beam (1a) by a vehicle (3a), where other vehicles (3b,3c) are arranged in the emitting area of the light beam. The latter vehicles emit other light beams (1b,1c). The former light beam of the data set is modulated by th...

A vehicle headlamp apparatus (30, 230) includes right and left lamp units (10) disposed away from each other in a vehicle width direction, each of the lamp units (10) being operable to form at least a low beam light distribution pattern (LoR, LoL) and a hi...

The system has a detection unit for detecting position and direction of travel of a vehicle, and a storing unit for storing a digital road map. An evaluation unit evaluates a digital road map depending upon the position and direction of travel of the vehic...

The second filament (2) operates at a lower power than the first filament (1) in order to perform a daylight running lamp (DRL) function. The reflector (R) has a lower reflective region (4) cooperating with the second filament to provide at least part of t...

The device controls at least one lighting device (3,5) depending on a readiness to drive condition by operating the lighting device(s) with reduced power. The lighting device is supplied with a pulsed supply voltage with a variable pulse width. The lightin...

The system has on-board vehicle light switching arrangements, an external dark zone position signal generation arrangement and on-board signal receivers. A photosensor controller and a position sensor controller are arranged in a circuit of a photosensor-p...

The method involves switching the lighting devices depending on the ambient conditions. The position and the time are detected as ambient conditions in which the vehicle is being operated and the external lighting devices are switched depending upon them. ...
