Nite Ize RideLit Red LED Light
The RideLit LED provides clear, obvious visibility for people who cycle at night. Its adjustable elastic band attaches to your ankle to create a moving circle of light or can be attached to the handlebar or bike seat post. Its bright LED can be seen for up to a mile away, and can be set to either steady glow or flash modes. The elastic strap is adjustable and removable, so you can wear, hang, or attach it wherever you like.
