Best lights

I have tried many lights for my bike, and Knog are my brand of choice. They keep going for hours on those really long bike rides, are bright, easy and quick to charge, don't have bits that fall off and cope in the rain. Great lights for any type of bike rider.

brightest rear light I've had. everyone says how well it illuminates my rear…..well the rear of my bike actually! Only criticism…..it slides off a little too easily.

Perfect little light

Compact, bright and surprisingly long battery life. Love that no cables are required to charge it.

‘Knog’s Cobber is an impressive light with a simple and elegant design.’

Why you'll love riding with Lil Cobber.

The world's only 330 degree rear bike light.

Simple Button

Lil Cobber Rear is simple to operate. A long press of the single button will turn the light on and off, and a short press will cycle through the modes. Cobber has a run time of up 40 hours.

Packed With Innovation

Efficient Chip on Board (COB) LEDs provide maximum brightness level for up to 90% of the battery burn time. As well as 5 pre-programmed modes, it’s compatible with Knog's ModeMaker app so you can customize your light modes.

Mount With Ease

Cobber comes with tool-less removable silicone straps for seat posts 22 – 32mm+ diameter and a magnetic mount. Also includes a standard and Aero mount.

Integrated USB Connector

Plug Lil Cobber directly into USB-A ports. When your Cobber is running low on battery, a red ring will light up around the button. This ring will turn green and then turn off once the Cobber is fully charged.
