This paper reports findings of research study designed to evaluate effectiveness of reflectorized headlamp under realistic night driving conditions; established parameter was distance at which unlit side of approaching one-eyed car could be detected for vehicles equipped with reflectorized headlamps and for vehicles equipped with conventional headlamps; variables considered were dry and simulated rain conditions, three rates of closure, and both sides of vehicle; mean detection distances established were 472 ft and 288 ft for reflectorized and conventional headlamp conditions respectively; as expected, all detection distances during conditions of simulated rain were reduced, but relative values were maintained.
