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.

Customer Reviews
I have been prompted to leave a review on my big Cobbler rear light, and I wish I could. I have not received this order. When I check my tracking number, it shows it never made it to ups or isn’t in their system. I was really looking forward to using this - inside in a busy major city and it’s dark early now. This large rear light I imagined would be a great addition to my evening visibility …. If I ever received it.
Wonderful lights
I love the Big Cobber rear light. It is amongst the very brightest of bright rear lights available, has a huge angular range of visibility and the design is incredibly elegant. I’m really impressed.
The Big Cobber is a great little unit. It is over priced for what it is. Easy to use.
Amazing product 👌🏽
