About Lezyne Strip Pro AI Alert 400+ Rear Light
Introducing the future of bicycle light technology - AI Alert. Combining Artificial Intelligence with our advanced ALERT rear taillights to 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 KTV Pro+ Ai Alert Rear is a premium, highly visible rear taillight combined with advanced Ai Alert technology. Equipped with super-bright LEDs providing a beam pattern optimal for light dispersion in even the most challenging conditions. The lightweight and durable co-molded construction with wide angle optics for 270degree of visibility, offers 6 combined solid and flash output modes- from the attention-grabbing max 150 lumens emitted in both Active Alert and Day Flash modes to the impressive 20 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 400 mAh battery capacity and an integrated USB stick allows convenient cable-free recharging.
