Big Cobber Rear Bike Light
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.
Big Cobber produces an incredible 330° of light, so you’ll be clearly seen from behind as well as from both sides. It’s brilliantly effective at attracting attention day and night, making it one of the safest rear bike lights you could choose.

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

Works according to the ads. I’m very happy with it.
As soon as I received it, I turned it on and went on my bike to try out! The light is super bright, all I was looking for! Next day went exploring with my husband in the woods and had to ride with the mtb on couples miles on the road before hitting the trails. So I put the light on so the cars can sees us. Once in the trail I forgot to take it off. We were exploring off trails and when we finally got back to the gravel road I checked my lights and it fell somewhere. I was sad. Because it’s not a trail that you follow I couldn’t go back to retrieve it. I’ll get a new one for sure, but I’ll
Wait for some discounts.
When this light worked, I loved it. However, less than two years in, water collected inside the light and it no longer turns on. Whenever I squeeze it, water comes out of the corners. I don't ride in heavy rains, but it's ridiculous that something that's meant to be used outside and is advertised as waterproof fails in this way. I received this as a gift, so there's no way for me to do a warranty return. I haven't heard anything from the manufacturer, and I do not think I'd purchase this myself.
