F21L LIGHTING DEVICES OR SYSTEMS THEREOF, BEING PORTABLE OR SPECIALLY ADAPTED FOR TRANSPORTATION
Introduced: September 1968
Description
F21L covers portable lighting devices and systems designed for mobility or transport applications. This includes hand-held lamps, flashlights, headlamps, vehicle lighting systems, and other illumination equipment where portability or integration with transportation modes is a primary design characteristic. The classification encompasses devices powered by batteries, combustion, or other sources, as well as lighting fixtures structurally integrated into vehicles or transport equipment. Adjacent classes F21S and F21V address stationary lighting devices and general lamp construction respectively.
