Smart Brake Sensing Bike Tail Light Auto On/Off Motion Sensor

Key features

• Smart Brake & Vibration Sensing: The light automatically activates a 2‐second high‐brightness solid beam when it detects deceleration or emergency braking, alerting vehicles behind you. A built‐in vibration sensor powers the light on as soon as you start riding and turns it off after 30 seconds of inactivity-no manual operation required, so you stay focused on the road.
• Hidden Tracker Pocket & Durable Aluminum Frame: Built-in discreet slot fits AirTag (not included) for convenient bike anti-loss tracking through Find My app. IP66 waterproof aluminum shell withstands rain and dust, keeping your bike and taillight safe during daily rides. Third-party accessory, no official Apple affiliation.
• 800mAh USB-C Rechargeable Battery with Low Power Reminder: Built-in 800mAh large-capacity battery supports 1-3 months of daily use per full charge. It flashes three times to remind you to recharge when power falls below 25%. Low-brightness flash during charging, and stops blinking once fully charged. Universal USB-C port works with power banks, laptop chargers and standard USB adapters.
• 4 Lighting Modes & 8 Adjustable Brightness with Memory Function: Choose from slow flash, breathing, strobe, and steady modes. The high-visibility strobe mode greatly improves safety for daytime rides. 8 customizable brightness levels fit dark rural roads and busy urban streets alike. The built‐in memory saves your last selected mode and brightness, so you don't need to reset it before each ride.
• Two Mounting Options for Universal Fit: Includes a sturdy seat‐rail clamp and a tool‐free elastic strap, allowing quick installation to seat posts, seat stays, saddle rails or cycling bags. Compatible with most bicycle types, this tail light suits daily commuters and recreational cyclists alike, offering flexible placement without extra tools.
