Lezyne KTV Drive Pro Smart Rear Bicycle Light, Red LED, Bluetooth, Black Housing, Road, Mountain, Gravel Bike, USB Rechargeable

Lezyne has fixed that issue with the KTV Drive Rear light.

Compatible with aero and round posts, this handy little light is powered by twin LED emitters that put out up to 10 lumens of light in five different eye-catching modes.

Using the brightest flash mode, you get a whopping 10 hours of battery life, and with the most minimal flashing mode you get an incredible 19.5 hours of illumination from this compact package.

Using the Smart Connect technology, you can pair this light with your phone to customize its lighting modes, and pair it with a front light for single button operation.

Built from a co-molded Composite Matrix body, this little powerhouse is IPX7 rated, meaning that even when you’re riding in the nastiest rainy conditions, you can rest assured that your rear light will continue to blaze away and help you stay safe.
