Bookman Visibility Curve

The light is designed with a curved lens shape that wraps around the sides of the unit. This allows the three LEDs to project light not just directly behind you, but also out to the sides, ensuring you are visible to traffic approaching from angles at intersections.

Yes, the flexible silicone strap is designed to stretch and accommodate a wide variety of seatpost shapes, including round, aero, and D-shaped posts. It is a universal, tool-free mounting system.

You can expect up to 32 hours of battery life on a single charge, though this will vary depending on which of the five lighting modes you select. It recharges easily via a standard Micro-USB cable.

The Bookman Visibility Curve is water-resistant, meaning it is built to withstand rain, road spray, and damp conditions during your commute. While it is durable enough for year-round use, it is not designed to be submerged in water.

While the seatpost is the standard mounting location, the flexible strap allows you to attach the light to other parts of the bike frame, such as the seat stays, provided the diameter is compatible with the strap's length.
