Lezyne Saddle Ai Alert 250 Rear Light
Introducing the future of cycling safety with the Lezyne Saddle Ai Alert 250 Rear Light, a groundbreaking blend of artificial intelligence and advanced ALERT rear taillight technology. This innovative light automatically detects brake events and seamlessly switches to Active Alert Mode - a rapid 250-lumen flash "brake light" - to signal deceleration, effectively communicating your movements to traffic and fellow cyclists for enhanced visibility and safety.
Featuring 10 super-bright LEDs, it delivers a powerful beam pattern designed for optimal light dispersion, even in challenging conditions. Built with durable CNC-machined aluminium and wide-angle optics for 270° of visibility, the light offers seven output modes, including the attention-grabbing 250-lumen Active Alert and Day Flash modes, and an impressive 60-hour runtime in FEMTO mode.
Tested to IPX7 waterproof standards, the Saddle Ai Alert 250 Rear is engineered to perform in any weather. With a battery capacity of 1100 mAh, it’s easy to recharge - simply unscrew the light from the saddle mount to access the USB-C charging port (cable not included).
