Note(s) This subclass covers devices or systems intended for fixed installation, e.g. vehicle lighting, or for use at a permanent location, e.g. free-standing floor- or table-lamps. [7] This subclass does not cover devices or systems specially adapted for transportation, which are covered by subclass Fulltext... Hierarchy... Expanded...F21L. [7] In this subclass, it is desirable to add the indexing codes of subclasses Fulltext... Hierarchy... Expanded...F21W and Fulltext... Hierarchy... Expanded...F21Y. The indexing codes should be unlinked. [7]
