With excerpts from AutoZeitung
AutoZeitung, the № 4 auto magazine in Germany, published in June the results of tests they conducted on 12 different premium, compact and small cars. Their headlamps were equipped with various light sources, halogen, xenon, LED and laser, and lighting systems ranging from mechanical ADB to matrix beam.
To judge the width of the light beams
and their homogeneity, static small
targets were spread at equal distances
on the ground
Light static range measurements were
performed on the landing surface
of a sporting airport by placing targets
Driving tests were conducted on a closed test track and on open roads and freeways.
