The Lezyne KTV Pro Alert Drive Rear Light is a compact, aero - post compatible rear bike light. It features a Daytime Flash mode and our unique 'Alert' technology, which is the ultimate solution for visibility.

Its co - molded construction is both lightweight and durable, with an IPX7 waterproof rating. This light can reach up to 75 lumens in Daytime Flash mode and has 6 output/flash modes. An integrated USB stick allows for convenient, cable - free recharging, giving you up to 14 hours of runtime. Max lumens: 75. Weight: 56g. Max runtime: 14 hours.




Using your Lezyne KTV Pro Alert Drive Rear Light is easy. First, make sure it's fully charged using the integrated USB stick. You can choose from 6 different output/flash modes depending on your needs. When you're riding, the light will work in its normal mode. Once you start to slow down, the light will turn solid to signal your deceleration to others. When you stop, it'll show a distinct flash pattern. After you start riding again, it'll go back to the previous mode. Remember to keep the light dry as it has an IPX7 waterproof rating, but don't submerge it for too long. If the light doesn't seem as bright as usual, it might be time to recharge it. It can run for up to 14 hours on a full charge, so plan your rides accordingly. Keep it clean by wiping it with a soft cloth. If you notice any damage, stop using it and contact customer service.
