| F 21 L | LIGHTING DEVICES OR SYSTEMS THEREOF, BEING PORTABLE OR SPECIALLY ADAPTED FOR TRANSPORTATION [1,7] |
|
| Notes |
|
| (1) | This subclass covers devices or systems designed or specially adapted to be carried, e.g. by hand, or otherwise transported from place to place, e.g. on wheeled supports, in order to provide illumination as and where required. [7] |
|
| (2) | This subclass does not cover devices or systems intended for fixed installation, e.g. vehicle lighting, or for use essentially at a permanent location, which are covered by subclass F21S. [7] |
|
| (3) | In this subclass, it is desirable to add the indexing codes of subclasses F21W and F21Y. The indexing codes should be unlinked. [7] |
