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 bike light system, this is the most accurate cycling brake light on the market.
The light automatically detects brake events and intelligently switches to
Active Alert mode – a rapid 150-lumen flash “brake light” that signals deceleration.
This effectively communicates your actions to both traffic and fellow cyclists, significantly improving rider
safety and visibility.
Ai Alert lights come pre-programmed and do not collect rider data.
The Strip Pro Ai Alert 400+ Rear pairs premium build quality with advanced Ai Alert technology.
Equipped with 10 ultra-bright LEDs and wide-angle optics for 270° of visibility,
it delivers optimal light dispersion even in the most challenging conditions.
The lightweight, durable, co-molded construction offers 7 combined solid and flash modes – from
the highly disruptive 400-lumen Day Flash mode to an impressive
80-hour runtime in Femto mode.
A versatile silicone rubber strap ensures compatibility with both aero and round seat posts.
Tested to IPX7 waterproofing standards and powered by a 1900 mAh rechargeable battery,
it features convenient USB-C waterproof charging (cable not included).
