## Abstract

This document amends the Federal motor vehicle safety standard on lighting to permit asymmetrical headlamp beams on motorcycle headlighting systems. This amendment will allow upper and lower beams to be emitted by separate dedicated headlamps on either side of a motorcycle's vertical centerline or by separate off center light sources within a single headlamp that is located on the vertical centerline. This action completes action upon the grant of a rulemaking petition from Kawasaki Motors Corp. U.S.A. and represents a further step towards harmonization of Standard No. 108 with the lighting standards of other nations.
