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.
The Big Cobber Rear Bike Light 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 lights you could choose.

I use the Big Cobber Rear Bike Light to commute on the road in the countryside and I feel really safe with it. I had the following small problem on a rainy day: small stones came to block the button and made the product unusable. With the vacuum cleaner I was able to unblock the button.
great light, love all the different modes and makes me feel safe riding at night!

These lights are obviously made very well. I love that I get some visibility on the side as well as from behind. The light is very bright, brighter than I expected it to be!
Lots of choices for attention-catching and very bright rear safety! Expensive, but well worth it.
