The Rapid X3 Rechargeable Rear Safety Light from CatEye is a lightweight, compact rear safety light that presents many mounting options and six operating modes. With a peak output of 100 lumens, it will assure that you are visible to riders and motorists behind you.
The light has high, low, flashing, rapid, pulse, and vibrate modes. Runtimes range from one hour on high to 30 hours on flashing, and recharging via USB takes about 3 hours.
The Rapid X3 protects against being caught with a dead battery with its innovative low battery auto save feature: when the power gets low, the Rapid X3 automatically switches to flashing, the most economical setting, to provide another hour of light.
With its O-ring-style rubber band attaching method, the Rapid X3 fits on round and aero seatposts, seatstays, handlebars, and forks, and is compatible with select CatEye mounts.
