RUNNING LIGHTS-CONSPICUITY AND GLARE

Measurements were taken of vehicle (including motorcycles) conspicuity and glare due to different running lights. Experiments were conducted in daylight and streelighted darkness. The intensities used were 50 cd (candelas), 150 cd, low beam (about 400 cd) and high beam (about 60,000 cd). Both white and yellow colored luminous areas were considered. Peripheral detection distance was the primary criteria for conspicuity, with secondary emphasis on foveal conspicuity. Results are presented, and suggestions are given for optimum running light characteristics. /HRIS/
