MOTORCYCLE HEADLIGHTING RESEARCH

A research program was conducted which: (1) Quantified the characteristics of currently available motorcycle headlamps; (2) examined the headlamp aim of 90 in-service motorcycles; (3) examined the eye fixations of two motorcycle drivers while operating a motorcycle in daylight; (4) provided subjective ratings of a number of quantitatively different low beam headlamps which were evaluated in terms of photometric characteristics of the lamps; (5) determined subjectively desirable headlamp aim by enabling 20 motorcyclists to aim a headlamp while driving at night at two different speeds; and (6) provided comparisons of the relative efficiency of a number of high and low beam headlamps in field target identification tests. Results of these studies indicate that motorcycle headlamps should distribute illumination in areas on and about the road surface that are not dealt with by the low beam motorcycle photometric standard (SAE J584) specified in FMVSS 108. New photometric standards, based on the various findings, are recommended for three classes of motorcycles representing three maximum speed categories.
