Implementation analysis for daytime headlamp use.

The study presents an analysis of the production feasibility, consumer cost, and schedule for implementing future regulations regarding a daytime lights-on policy where the headlights are automatically turned on whenever the engine is operating. This action would promote traffic safety through better vehicle visibility. The proposed effective date for "Lights On" is 1984 model new vehicle production. Vehicle types covered include Mopeds, Motorcycles, Passenger Cars, Light, Medium, and Heavy Duty Trucks, Multipurpose Vehicles, and Buses. Evaluations are made for the feasibility of the present vehicle fleet to operate with headlights on full time. Summary tables for each type are provided showing initial and annual costs for this proposed safety feature.
