8512.10 - Lighting or visual signaling equipment of a kind used on bicycles:

Heading 8512.10 specifically encompasses lighting or visual signaling equipment designed for use on bicycles. This includes, but is not limited to, headlamps and taillights that illuminate the path or signal the presence and direction of a bicycle to other road users. The key defining characteristic for this heading is the intended application on bicycles, distinguishing it from more general lighting or signaling devices.

Within the broader heading 8512, this subheading is differentiated from sibling categories such as 8512.20, which covers other lighting or visual signaling equipment not exclusively for cycles, and 8512.30.00 for sound signaling equipment. It also excludes parts of such equipment covered under 8512.90 and equipment like windshield wipers under 8512.40.

The subcategories within 8512.10 further refine the classification based on function. 8512.10.20.00 covers the "lighting equipment" aspect, focusing on devices that produce illumination. In contrast, 8512.10.40.00 addresses "visual signaling equipment," which primarily pertains to devices that signal the bicycle's presence or intent, such as flashing lights or reflectors that are actively used for signaling purposes, rather than solely for illumination.
