Big Cobber Bike Light Twinpack
Lumens are a measure of the total amount of visible light from a light source. The higher the lumen rating the “brighter” the light will appear.
The Big Cobber Bike Light Set produces an incredible 330° of light, so you’ll be clearly seen from in front, behind and from both sides. They're brilliantly effective at attracting attention day and night, making this light set one of the safest you could choose.

18 factories told us Cobber would be impossible. We were happy to prove them wrong.

I’m returning and buying the big cobbler rear light as a standalone. The front makes you visible, but does nothing to light the road since it’s so disbursed. For the same price as a big cobbler front, I’ll buy a PWR light that both keeps me visible and actually lights the road in front of my bike. I give the rear 5/5 for both brightness and visibility, but front is a 1/5 for usability so I split the difference.
Hey Ryan, firstly, thank you for sticking with Knog! You're right of course, Cobber front lights are in our 'Be Seen' category, great for attracting attention day & night in urban environments where street lighting etc lights your path ahead. If you're looking to light up dark roads / trails, a Knog 'See By' light is the way to go. If you can't find a PWR front light (they've been discontinued), we've just launched a new Blinder collection (June '23) which comes with 600, 900 & 1300 lumen options. All the best!
I started commuting by bike sixteen years ago and I’ve gone through a lot of lights and these, so far, are the best lights I’ve used.
Just used on a 120 mi ride and these lights worked the entire time longer than the stated durations.
I really liked these lights but I only got to use them for a week before my bike got stolen with the lights on it (._.)
Super bright and awesome light modes, I'd fersuree buy these again.
great light , seen from all angles
