KTV Pro+ AI Alert Rear Light

The Lezyne KTV Pro+ Ai Alert Rear is a compact rear light that adds smart brake detection to a simple, everyday safety light. It can put out up to 150 lumens, with Wide Angle Optics providing visibility from a broad 270° arc. The Ai Alert system detects braking and increases the light's output to make changes in speed more noticeable to following traffic. Its small co-molded body, flexible O-ring mount, and IPX7 waterproofing make it well suited to daily riding in all kinds of weather.

Who It's For
The KTV Pro+ Ai Alert Rear is for commuters, road riders, gravel cyclists, and anyone who wants a compact rear light with an extra layer of active visibility. The brake-sensing function is particularly useful in traffic because it gives following riders an additional visual cue when you're slowing down, without requiring you to think about activating a separate brake-light mode.
