The ROCKBROS Magnetic Bike Tail Light is a smart, waterproof rear light designed for serious cyclists who want quick installation, reliable visibility, and responsive braking signals in any weather. With magnetic mounting, multiple lighting modes, and an integrated brake sensor, it keeps you seen and safe on every ride.

• Effortless Magnetic Mounting: Quick, tool-free installation with a strong magnetic suction that sticks securely to frames or seat posts, even on bumpy roads. Removable in seconds for easy transportation or swapping between bikes.
• 7 Lighting Modes + Brake Sensor: A bright 0603 red LED array offers seven modes—single flash, double flash, strobe, water drop flash, breathing flash, back-and-forth flash, and a long steady light. The sensitive brake sensor detects speed changes and automatically elevates brightness for 1.5 seconds to warn following traffic.
• Wide Visibility & Waterproof Protection: Fan-shaped light layout provides up to 200 meters of visibility with 270° side-to-side coverage, enhancing awareness from behind and the sides. IP-rated waterproofing keeps performance reliable in rain and mist.
• Auto & Manual Dual Modes: Auto mode powers on in low light and sleeps after 2 minutes of inactivity for hands-free operation; manual mode gives you direct control with one-click flashing or steady light options.
• Long Battery Life & Easy Charging: A compact 400mAh battery supports up to 36 hours of runtime in flash mode. USB Type-C charging is quick, and built-in LED indicators alert at 30% and 10% remaining so you’re never surprised.

Designed for night commutes, road rides, and weather-prone conditions, the ROCKBROS Magnetic Bike Tail Light prioritizes safety without fuss. Its lightweight 36g footprint and durable PC+ABS construction, paired with a silicone-based base and magnet, deliver a reliable, highly visible rear light that’s simple to mount, remove, and recharge—so you can focus on the ride ahead.
