THE PROBLEM OF HALOGEN LIGHT. PERCEPTION OF OBJECTS ON THE ROAD IN RELATION TO VARIOUS TYPES OF HEADLAMPS ON MEETING VEHICLES

PROBLEM HALOGENLICHT. DIE WAHRNEHMUNG VON GEGENSTAENDEN AUF DER FAHRBAHN IN ABHAENGIGKEIT VON VERSCHIEDENEN SCHEINWERFER LICHTSYSTEMEN ALS GEGENLICHT

In studying the question as to whether and to what extent conventional headlight systems and halogen headlight systems affect the perceptibility of objects on the road, it becomes apparent that halogen light on an opposing vehicle, in comparison with conventional light on an opposing vehicle, delays the perceptibility of objects in darkness. This is particularly so for full-beam and dipped headlights. However the use of halogen fog lights on an opposing vehicle increases perceptibility. The results are discussed together with Swedish and American studies on the problems of vision in darkness. The problem of the perceptibility of different shaped objects is also considered. /TRRL/
