CatEye - Rapid Mini Rear Bike Light, 25 Lumens

Specifically designed for minimalists, the USB-rechargeable Rapid Mini offers 4 modes of eye-catching illumination. At only 22 grams, whether it's on a seatpost, Fizik saddle or messenger bag, extra weight and bulk are no longer excuses for not being seen. Small in size but big on safety, the Rapid Mini has all the features of its big brothers of the Rapid X series, including low battery indicator, battery auto save, and mode memory.
