ADVANCED HEADLIGHTING SYSTEMS

Linearly polarized headlighting systems reduce the glare from opposing headlamps simply and effectively. This program was undertaken to evaluate the possible glare reduction measures. Alternative systems examined included circular polarization of light, color discrimination and stroboscopic (time-share) systems. Circular polarization is the only practical competitor to linear polarization. Laboratory and road test measurements showed that both are equivalent in performance and that both are significantly better than the present high-beam/low-beam system. Conversion to linear polarization is recommended during a five-year period from 1981 to 1985.
