Black round bike rear reflector light with seatpost mount

This bike rear light features a circular red lens with a textured honeycomb-style surface pattern. The housing is compact and mounted to the seatpost using a clamp-style bracket with a visible tightening screw. The design includes a detachable front cover, revealing an internal compartment behind the lens. The mounting system sits just below the saddle and connects with a structured bracket that allows angle adjustment. The overall appearance is minimal, with a matte black finish and a centrally positioned round reflector.
