Easily and securely mounted on a bicycle tube diameter of 2-3 centimeters, for example, on a handlebar.
Not slip, do not fall off when shaking.
Resistant to rain, and even work in a flush from the tap.
Quickly removed, fixed it seems long-lived if used carefully.

This light does not illuminate the road.
