When the cyclist decelerates their rear light will automatically switch to a distinct brake light mode to signal a decrease in speed to anyone behind enhancing visibility and safety while riding
Introducing the future of bicycle light technology- Ai Alert. Combining artificial intelligence with our advanced ALERT rear taillights will bring you the most accurate cycling brake light on the market. The light automatically detects brake events and intelligently changes output mode to Active Alert - a rapid 150-lumen flash “brake light” mode; signaling deceleration, effectively communicating your actions to traffic and fellow cyclists, enhancing rider visibility and safety.
*Ai Alert lights come pre-programmed and do not collect rider data.
The Strip Pro Ai Alert 400+ Rear is a premium, highly visible rear taillight combined with advanced Ai Alert technology. Equipped with 10 super-bright LEDs providing a beam pattern optimal for light dispersion in even the most challenging conditions. The lightweight and durable co-moulded construction with wide angle optics for 270° of visibility, offers 7 combined solid and flash output modes- from the highly disruptive max 400 lumens emitted in Day Flash mode to the impressive 80 hours of runtime in FEMTO mode. A versatile silicone rubber mounting strap attaches to aero or round seat posts. Rigorously tested to IPX7 Waterproofing standards to ensure functionality in the toughest weather conditions. The light also features a 1900 mAh battery capacity. With USB-C waterproof charging (cable not included).
