Lezyne Strip Pro Ai Alert 400+ Rear

When the cyclist decelerates, their rear light will automatically switch to a distinct 'brake light' mode to signal a decrease in speed to anyone behind, enhancing visibility and safety while riding.

Introducing the future of bicycle light technology- Ai Alert. Combining artificial intelligence with our advanced ALERT rear taillights will 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.
