Comparison of Halogen and Xenon Headlamps in Terms of Pedestrians’ Visibility

Abstract

This case study presents a comparison of visibility and recognisability (discernibility) of objects – pedestrians – on the road in rural areas at night on encounter with low beam headlights fitted with halogen lights and xenon (high-intensity discharge) lights in one and the same vehicle model. The study was inspired by the results of dynamic measuring of the reactions of vehicle drivers to the presence of pedestrians on the right side of the roadway, where the results indicated subsequent reactions of drivers driving a vehicle fitted with xenon discharge lights. The study is therefore concluded with a static comparison that confirms the factual findings.
