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.

Customer Reviews
This is my second set of Knog lights. My Lil Cobber lights are still going strong after 5+ years. Got the Big Cobbers on sale recently and so far so excellent. They are big (as advertised), but I like to be seen when riding for fun or commuting. I'm amazed by how long a charge lasts on Eco Flash mode and how easy to use and charge these are compared to other designs. I had to warranty one of my Lil Cobbers & the customer support was excellent even during peak Covid. Highly recommended.
The lights work as advertised but the size is too large. I’m having trouble getting them exchanged or returned. And the product information sheet is ridiculously small! I’d leave a picture of it here but there’s nowhere to leave a photo!
I submitted a complaint about receiving a broken part and never heard back, so i have yet to use the bike lights as intended.
These are really nice, and very visible lights, everyone who rides out on the roads should be using them!
These are great lights. Very bright. Probalby the best rear light that Ive used.
