Knog Big Cobber Tail Light

The 270-lumen output is exceptionally bright, designed specifically to grab attention from a wide range of angles. Because it offers 360-degree visibility, it ensures you are seen not just from directly behind, but also from the sides, which is critical when navigating intersections.

No, you don't need any cables. The light features an integrated USB plug that connects directly to a USB port, making it incredibly convenient to charge on the go or at your desk.

Yes, the light uses a tool-less mounting system with silicone straps that provide a tight, secure fit on various seat post shapes, including aero posts. It is designed to stay firmly in place even when riding over bumpy terrain.

Absolutely. While it comes with 8 pre-programmed modes, you can connect the light to the Knog ModeMaker app on your computer to customize the flash patterns and brightness levels to suit your specific riding environment.

An IP67 rating means the light is fully protected against dust and can withstand immersion in water up to one meter deep for 30 minutes. You can confidently ride through heavy rain or puddles without worrying about the electronics failing.

There is a convenient battery indicator ring located around the power button. It provides a clear visual cue regarding your charge status, so you won't be caught off guard by a dead battery mid-ride.
