Nite Ize RideLit LED Ankle Bike Lights, cyclists who ride at night or early in the morning know how crucial visibility is to their personal safety. The Nite Ize RideLit was designed to clearly and effectively tell your fellow commuters not only where you are, but also which direction you're heading. Its bright L.E.D. bulb 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. The RideLit is available in red and white: two colors that universally signify front and rear. Strap a white Nite Ize Ride Light on one ankle facing forward, a red RideLit on the other facing to the rear, and at a glance, everyone around you will know whether you're coming or going.(We've also included a hook and loop adhesive strip that connects to the Ride-Lit 's back, for optional semi-permanent placement on the front or back of your bike.) Powered by two long-lasting lithium batteries, (included), the RideLit bicycle light also comes with an extra set of replacement batteries.
