End rear visibility risks on rides with automated alerts
Enhance safety on evening rides with motion-activated signals and brake alerts — bright 80 lumen output with 64 LEDs, laser lane projection, and tool-free installation.

Why is this motion-activated rear light perfect for you?
✔ Motion-activated turn signals improve rider visibility.: This tail light activates directional arrow signals when the bike tilts 10 degrees left or right, flashing six times to alert drivers behind of turning intentions clearly, reducing accident risk at intersections.
✔ Automatic brake detection signals sudden stops instantly.: Integrated sensors trigger all 64 LEDs to flash six times upon braking, ensuring drivers are aware of sudden deceleration to enhance safety during rides.
✔ Laser lane projection defines riding space with visible borders.: An infrared laser projects a safety border on the pavement behind the bike, clearly marking the riding area for passing vehicles and increasing rider protection on the road.
