Harley-Davidson X440 / X440 OBDII Tail Light / Tail Lamp OEM | HDH33700RAA001

Replace a broken, cracked, faded, or non-working tail light with this genuine OEM tail lamp unit for Harley-Davidson X440 series motorcycles. Part number HDH33700-RAA-001 is listed in the genuine parts record as UNIT TAIL LIGHT. In buyer language, this is best understood as the tail light, tail lamp, or rear light.

This part is fitted at the rear of the motorcycle and is an important lighting and visibility component. If the original tail light housing is broken, the light unit is damaged in a fall, or the rear lamp is no longer functioning correctly, replacing it with the correct OEM assembly helps restore proper rear visibility and the factory look.

Public X440 image pages also use buyer-facing terms like tail light and tail lamp, which supports using those search-friendly names in addition to the OEM term UNIT TAIL LIGHT.
