VISIBILITY EFFECTS OF A RAPIDLY FADING HIGH BEAM AS AN OPTION TO THE ORDINARY LOW BEAM

Driver visibility has been measured just after dipping from high beam to low beam in simulated full-scale opposing situations. Two headlight conditions have been compared: an ordinary low beam (conforming to the ECE Regulation R20) with and without a high beam which is fading after dipping during a period of 6-10 seconds.
