Smart High-Brightness Brake Tail Light features 300-lumen ultra-bright XPE LED beads and a 220 wide-angle warning design, ensuring visibility from 500~1000 meters for enhanced nighttime riding safety. Equipped with intelligent light sensing, it automatically activates in low-light conditions (e.g., tunnels/nighttime) and turns off in daylight to save energy.

With 8-level brightness adjustment and 4 lighting modes (slow flash/breathing/strobe/steady), the strobe mode is recommended under strong sunlight for maximum alertness. Smart brake sensing instantly switches to 300-lumen strobe mode when decelerating, warning trailing vehicles to maintain a safe distance.

Crafted from aviation-grade aluminum alloy, this lightweight (46g) light boasts IP66 waterproofing, resisting heavy rain and harsh weather. The built-in vibration sensor puts the light into sleep mode after 30 seconds of inactivity; a gentle tap wakes it up, preventing battery drain.

Power-off memory retains your last settings for next use. Extended Battery Life: 1~3 months of regular use or 4~8 months in standby mode. Includes 3 universal mounts (nylon round tube/aero tube/saddle rail) for easy installation on bicycles, e-bikes, and tricycles.
