Lezyne KTV Drive Pro+ Alert Rear

The Lezyne KTV Drive Pro+ Alert Rear does more than keep you visible — it reads your movement. Built with an integrated accelerometer, the light automatically triggers a braking signal when it detects deceleration, communicating your slowdown to the traffic behind you without any input from your hands. It's a genuinely useful feature for commuting, group rides, and any situation where predictability matters.

Output tops out at 150 lumens across six modes, including flash patterns, a daytime running mode, and economy modes that extend runtime up to 20 hours on a single charge. A 270-degree visibility angle means you're seen from the side as well as behind — relevant at intersections and roundabouts where oblique sightlines are the norm. The light is fully waterproof and charges via an integrated USB stick that folds directly into the housing, so you're not hunting for a cable.
