Numen Aero TL Tail Light

Giant's Numen Aero Taillight is small, powerful and impressively bright. It's so sleek and light that it almost disappears. Come nighttime, though, cars will notice its three bright LEDs. It has a run time of up to 90 hours and features three modes: steady, flashing and chasing. The tool-free rubber mount easily attaches to most seatposts, including aero and integrated models.
