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.

Easy to work first thing in the morning, very secure attachment both things I need when heading out first thing especially in winter
Great bright light, the only light you’ll ever need. Attached to bike very easily, charges easily as well. Definitely worth considering.
This is the best light I've owned! So bright and I feel safer at night knowing others can see me from all angles, especially on roundabouts. Took note of other comments about them coming loose and seen a couple of people that have lost them... easy fix... I use a thin velcro strip that goes around the centre of the light and seat post. Can't go anywhere! I think the only thing I would change on this is the mount, and I'd love to see other mounting options for it.
An excellent light that provides you with peace of mind that you will be seen! Long lasting, rechargeable and easy attachment options.
This light has blinked happily on the back of my bike though city commuters and country backroads. Many people have commented on it… its very visible from the back and the side. So easy to charge just plug into a USB port no cables to find/ loose /remember. Amazing to be able to choose your own flashing sequence through the app. Great Aussie product.
