The Lezyne Hecto Drive Rear complements its Front counterpart perfectly, delivering a highly visible 15 lumens in Flash and Blast modes. The Side Visibility design allows 180 degrees of visibility and increases user safety. The light easily attaches to a wide range of round seatpost diameters via a snap-fit Composite Matrix mount, with a multi-position silicon rubber strap for tool-less installation. The dedicated rear mount points upward to ensure light is directed straight back. • Bright 15 Lumens
