Agency Aims to Cut Vehicle Light Glare

A government safety agency proposed reducing the brightness of daytime running lights in new autos after receiving hundreds of complaints about glare. The National Highway Traffic Safety Administration plans within two years to cut the maximum light intensity allowed for the front safety lights on new vehicles to roughly half that allowed now. In four years, the intensity would be reduced to a quarter of today’s brightest running lights. The agency is seeking public comment on the proposal before it issues a final ruling. The agency has received more than 400 complaints about glare since 1993 when the agency first allowed the lights.
