Stay visible, stay protected. This ultra-bright smart bike tail light combines advanced brake sensing technology with automatic operation to keep you safe on every ride. Whether you’re cycling through city streets or cruising at night, the light instantly brightens at maximum intensity when you brake — alerting drivers and riders behind you. Designed for smart convenience, it switches between manual and auto mode with just a double-tap, so you’re always in control.
In auto mode, the light uses a built-in motion and light sensor to detect your movement and the surrounding brightness. It turns on automatically at night or in tunnels, then powers off after 30 seconds of inactivity to save energy. Touch your bike or start pedaling, and it lights up again — no buttons, no hassle. In manual mode, you can manage power yourself for full control.
Customize your visibility with 6 lighting modes including Constant On, Breathing Flash, Slow Flash, Fast Flash, Rhythmic Flash, and Eco Flash. The IPX5 waterproof design makes it a reliable companion through rain, splashes, and dust, so your safety isn’t limited by the weather. Powered by a long-lasting 420mAh rechargeable battery, it offers up to 9 hours of continuous illumination on a single charge.
Mount it your way with included saddle brackets and adjustable silicone straps — perfect for seat tubes or saddle rails. Its rugged, weather-resistant build ensures performance in all conditions, while the charge indicator keeps you informed about remaining power, so you never get caught off guard.
Ideal for night rides, commuting, mountain biking, or any time you want to boost your rear visibility. With its smart sensing and powerful illumination, this tail light makes every journey safer, smarter, and easier.
Upgrade your cycling experience today — install this smart brake-sensing tail light and ride with confidence, no matter where your adventure takes you.
