Next-level safety, powered by Ai. Meet the Strip Pro Ai Alert 400+ Rear—a taillight that thinks ahead. This premium rear light integrates cutting-edge Ai Alert technology with Lezyne’s proven ALERT system to deliver the most intuitive brake light function on the road. It automatically detects when you slow down, kicking into an ultra-bright 150-lumen Active Alert flash that instantly communicates your movements to drivers and riders behind you—no lag, no confusion, just smarter, safer visibility.

With 10 ultra-bright LEDs and a beam optimized for wide dispersion, this light delivers up to 400 lumens in Day Flash mode and runs up to 80 hours in FEMTO mode. Seven output settings, 270° visibility thanks to wide-angle optics, and a rugged, co-molded waterproof build (IPX7 rated) make it a reliable companion in any weather. The 1900 mAh battery charges via USB-C (cable not included), and a flexible silicone strap mounts easily to aero or round posts. No apps, no data collection—just intelligent safety, straight out of the box.
