The TL-LD700-R Rapid X Rechargeable Rear Bike Light from CatEye is a lightweight, compact rear safety light that presents many mounting options and six operating modes. With a peak output of 50 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 2 hours.
The Rapid X protects against being caught with a dead battery with its innovative low battery auto-save feature: when the power gets low, the Rapid X 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 X fits on round and aero seatposts, seatstays, handlebars, and forks, and is compatible with select CatEye mounts.
