The Busch + Müller Secula Plus is the perfect dynamo powered LED rear light for seat stay mounting.
LineTec technology creates a light band around the reflector with a patented lens system and high-power LED. Hence it has an extremely bright light exit at 320° for all round visibility.

As with all German lights, it has a stand light which remains on while you are stopped at traffic lights, and over-voltage protection.

Comes with head light lead.

This version is designed to attach to your seat post. Includes seat post attachment.
