5 LIGHT MODES: The ROCKBROS bike tail light offers five lighting modes: red flash, red/blue alternating, colorful breathing, rapid strobe, and red steady-on. Switch between modes for commuting, night riding, road cycling, or low-light conditions to improve rear visibility and add a distinctive look to your bike.
DUAL MOUNTING: Includes both saddle-rail and seatpost brackets, giving you two flexible ways to mount the rear bike light. The tool-free, quick-release design makes installation and removal fast and convenient, while easy detachment lets you carry the light with you when your bike is parked.
USB RECHARGEABLE: Built-in rechargeable battery provides up to 50 hours of runtime depending on the selected mode. Four blue LED indicators display remaining battery power in 25% increments, helping you know when it is time to recharge. Charge conveniently from a computer, power bank, or compatible USB adapter.
IPX5 WATER RESISTANCE: Rated IPX5 to handle rain and splashes during everyday cycling. The sealed construction helps protect the bicycle rear light during commuting, road rides, and changing weather conditions. Designed for normal wet-weather use; do not submerge the light in water.
ALUMINUM ALLOY BODY: Lightweight aluminum alloy housing provides durable everyday protection without unnecessary bulk. A premium optical lens and COB LED create bright, evenly distributed illumination to help improve rear visibility during night riding, commuting, and road cycling.
