This paper summarizes research conducted to investigate the problem of forward visibility while driving during inclement weather. A review of the literature indicates that using narrow-distribution lamps, mounted away from the driver's line of sight, would result in the lowest amount of back-scattered light. The literature also indicates that the spectral content of light can influence glare and fatigue experienced while driving under these conditions. A series of investigations summarized in this paper confirm the review of the literature and appear to indicate that beam distribution and mounting position offer more leverage to vehicle designers than spectrum, for minimizing discomfort and glare while driving during adverse weather. The development of adaptive forward-lighting systems (AFS) for vehicles also offers promise for the modification of forward lighting distributions optimized for inclement weather. Indeed it is likely that AFS systems in the future will include automatic sensors to detect inclement weather and automatically modify the forward lighting distribution (and its spectral content) accordingly.
