This analytical study evaluated the performance of 40 first-generation low-beam headlamps that were either visually/optically aimable (VOA) or that met the GTB harmonized beam pattern, by comparing these low beams to conventional U.S., European, and Japanese low beams. The following aspects of headlamp performance were considered: visibility of pedestrians, visibility of pavement delineation, visibility of retroreflective traffic signs, visibility of vehicle rear reflex reflectors, visibility of targets near the road expansion point, glare directed towards oncoming drivers, glare directed towards rearview mirrors of proceding drivers, glare reflected from wet pavement towards oncoming drivers, and foreground illumination. The results are presented separately for the VOA lamps that are aimable on the left side (VOL lamps) and the right side (VOR lamps), as well as for the harmonized lamps.
