Bell Sports Arella X50 USB Tail Light

Bell’s Arella Series bicycle lights utilize super bright, flat LED technology allowing you to “Be Seen” by traffic in low light conditions. The Arella X50 rechargeable tail light uses a silicone mounting strap for quick and easy, no-tools installation on nearly any size seat post. This tail light can be run in steady, strobe, or flash modes. When the time comes for recharging, plug the light directly into a USB port - no cable needed. And because all Bell lights are tested and rated to industry-recognized FL-1 standards, you can rest assured they perform as advertised. Uses 2 AAA batteries (not included). Specifications: Brightness: 30 lumens; Run time: 1 hour (steady) / 3 hours (strobe) / 4 hours (flash).
