THE RELATIVE MERITS OF DIFFERENT LOW BEAM HEADLIGHTING SYSTEMS. A REVIEW OF THE LITERATURE
The report covers the historical development of automotive headlighting and describes the differences between European and American concepts in terms of photometrics and construction. The advantages and disadvantages of each system are described. The main section of the paper is a description of research comparing European and American headlighting systems. There are a number of such studies. The most usual finding is one of small or no differences in seeing distances. The few studies which report larger differences do not agree which system is better. It is concluded that there is presently no objective way of determining which headlighting system is better. What is clear is that headlighting is a complex subject and the available research evidence, even if it favored one system or the other, covers only some aspects of the problem.
