The primary purpose of the study was to collect information on the condition of lighting equipment, rearview mirrors, and tires on a nation-wide sample of vehicles in use. In order to more adequately represent cars of the future, the sample was restricted to vehicles built in 1979 and later. The results of the study indicate that headlamps are often badly out of aim. About 60% of the vehicles sampled had one or more low-beam units aimed outside of SAE limits. Aim worsens as vehicles age, at least for the first four years. The rearview mirrors in the sample were generally in good physical condition. About 90% of the tires in the sample were found to be free of defects. A study was also run of the effects of vehicle loading on vertical headlamp aim. Literature surveys were also run on aerodynamic effects, and equipment for cleaning headlamps and maintaining their aim under different loading conditions. Summaries of the findings are presented.
