Last updated: August 2026 dataAutomotive and industrial aftermarket supply chains rely heavily on this category, which captures replacement and OEM components for vehicle lighting assemblies, turn-signal systems, windshield wiper mechanisms, and defroster/demister units — but explicitly excludes the lamp bulbs themselves (filament, discharge, or arc types). Classification discipline matters here: a housing or reflector assembly belongs in this heading, while the lamp element it holds does not. Importers sourcing wiper motor sub-assemblies or lighting harness brackets should confirm that the part's principal function aligns with the parent equipment rather than with a separately classifiable electrical component.

No. This heading explicitly excludes filament, discharge, and arc lamps. Only structural and functional parts of the lighting or signaling assembly — such as housings, reflectors, and mounting brackets — fall here; the lamp elements themselves are classified separately.
Classification turns on the component's principal function. If the module is integral to the wiper drive mechanism and not separately identifiable as a standalone electronic controller, it typically follows the wiper assembly classification. Complex multi-function units should be reviewed with a licensed customs broker to determine the correct heading.
