Front light very bright for being noticed.

Don't know why there isn't a wider clasp for mounting. A number of comments on Amazon site mentioning this!

Definitely be seen, not see category

These are amazing. As the title says, they're super visible. Slightly worried about blinding pedestrians at night.. Being able to set your modes via the application is great though, ended up with just three modes I really liked. Mix of ones for use in traffic and for bikeways etc

'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.
