The Lezyne KTV Pro+ AI Alert is a rear light that uses Ai Alert technology to detect deceleration and automatically switch to a rapid 150-lumen Active Alert flash, functioning as a brake light. Wide Angle Optics extend visibility to 270 degrees, helping alert following traffic to a rider's presence and any change in speed.
The lightweight, 50g co-molded housing is rated IPX7 for waterproofing and mounts to aero or round seatposts using a silicone strap. Six solid and flash modes, including a Day Flash setting, plus an integrated USB stick for cable-free recharging give riders a durable, low-maintenance light with up to 20 hours of runtime in Femto mode.
