Light up day and night.

I’ve had big cobbler lights for a few years now and would recommend them. During the day I have them on a dim flash. At night bright flash. The battery lasts a reasonable length of time. Easy to swap over to my other bikes.

I thing these lights are the "Cats Meow"

Top Notch Equipment!

I love these lights, I swear you could see my bike from space at night when I have both of them going. People always compliment how they look and I always recommend that they check em out! I love them for visibility on the road and I feel safe when I have them on.

Big cobbler light pack

Love the Brightness of both lights. Love the custom light setting feature. Concerned about losing the lights going over gravel bumps off road !

'this is simply the best bike light set for attracting the attention of other road users.'

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

Why you'll love riding with Big Cobber.

The world's only 330 degree bike light.

Simple Button

Big Cobber bike lights are simple to operate. A long press of the single button will turn the lights on / off, and a short press will cycle through their modes.

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 8 pre-programmed modes, both are compatible with Knog's ModeMaker app so you can customize light modes.

Mount With Ease

Cobber comes with removable silicone straps for handlebars / seat posts 22 – 32mm+ and head tubes up to 200 mm in diameter. Aero & standard mounts included.

Integrated USB Connector

Big Cobber plugs 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, then off once fully charged.
