FIELD EVALUATION OF RECTANGULAR HEADLAMPS

An analytical and empirical investigation evaluated use of rectangular headlamps during the present interim allowance period. If the option is extended, it is forecast that 77 million passenger cars with rectangular headlamps will be on U.S. roads in 1985, about 62 percent of the forecast 1985 passenger car registrations. Telephone interviews were conducted with a representative sample of owners of 1975 automobiles equipped with rectangular headlamps. Results are reported. A survey of GMC dealers, service stations, unaffiliated parts suppliers and general retail outlets, indicated where the rectangular lamps are available. Mechanical aimers are discussed.
