TOSUOD TS-WD113 Bicycle Tail Light Auto Brake Sensing Rear Light

TOSUOD TS-WD113 Tail Light Safety Features and Smart Brake Detection

The auto brake sensing technology activates high-brightness mode when deceleration exceeds a preset threshold, triggering a flashing warning pattern that alerts drivers riding closely behind your bike. This rear light adapts to real-world riding scenarios where sustained illumination provides baseline visibility and sudden brightness increases create a psychological impact that prevents rear-end contact incidents. Long duration runtime stretches across weeks of daily commuting when charged through standard USB ports on computers, chargers, and power banks. USB recharging eliminates proprietary battery cartridges and connector incompatibility, letting you charge at home, office, or any location with USB infrastructure already present. The durable housing mounts securely to seat tubes, seat stays, and rack frames, accommodating various bike geometries and cargo setups without compromising light visibility angles.
