Enhance your cycling safety with the ROCKBROS Magnetic Smart Tail Light. Featuring innovative brake sensing technology that automatically brightens when you slow down, this IPX6 waterproof light ensures visibility in all weather conditions. The convenient magnetic mount allows for quick attachment and removal, making it the perfect companion for your daily rides or adventures.

Stable Magnetic Mounting

Enjoy tool-free installation with a secure magnetic attachment. High-strength magnets keep the bike rear light firmly in place, even on bumpy rides, preventing any vibration-related loosening.

Smart Dual Mode Operation

Easily switch between auto and manual modes with a double-tap. The auto mode utilizes motion-sensing technology, automatically turning off after 2 minutes of inactivity and reactivating with vibration for optimal energy efficiency during commutes or stops.

7 Versatile Lighting Modes

Effortlessly cycle through seven lighting options with a single button: Simple Flash (36h47min), Double Flash (27h27min), Rapid Flash (13h51min), Waterdrop Flash (31h14min), Breathing Flash (12h42min), Back-Forth Flash (13h16min), and Steady Light (8h3min).

Brake Induction Safety

Enhance your nighttime cycling security with automatic activation of high-brightness mode (200m visibility) upon detecting sudden deceleration. This feature maintains intense illumination for 1.5 seconds, alerting vehicles and pedestrians.

IPX6 Waterproof & Smart Battery

The 400mAh battery supports extended rides with low-power alerts (30%: slow red blink; 10%: rapid blink). The rainproof design withstands heavy showers, though prolonged submersion should be avoided.
