Lezyne Strip Pro Ai Alert 400+ Rear Bike Light

The future of bike lighting lies in Ai Alert technology, which incorporates artificial intelligence to deliver the most precise rear light. This system automatically detects braking and switches to "Active Alert" mode, a rapid 150-lumen flash to signal deceleration and improve visibility for vehicles behind. It effectively communicates your actions to other cyclists and vehicles, thereby increasing safety. Ai Alert lights are pre-programmed.

The Strip Pro Ai Alert 400+ Rear is a high-end rear light, featuring 10 ultra-bright LEDs for optimal illumination, even in challenging conditions. It offers 7 lighting modes, ranging from 400 lumens in daytime flash mode to 80 hours of battery life in FEMTO mode. Its lightweight construction, IPX7 waterproof rating and compatibility with aerodynamic or round seatposts make it a practical choice. Finally, it features a 1900 mAh battery and charges via a waterproof USB-C port (cable not included).
