Fog Lamps: Frequency of Installation and Nature of Use

摘要

The goal of this study was to provide information about the frequency ofinstallation and use of fog lamps. Two surveys were performed. In the first one, installation of fog lamps was estimated by a survey of parked vehicles in two large shopping centers. The second survey studied the usage of fog lamps during daytime and nighttime, under clear, rainy, or foggy conditions. In this survey, an observer in a moving vehicle noted the types of lamps were energized on the fronts of oncoming vehicles, and whether fog lamps were installed at all.
