Cobber Reflex 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.
Cobber Reflex Rear is engineered to adapt to the ride. Using intelligent Reflex modes, it adjusts to your bike’s speed and angle, maximising visibility when it matters most. Smart, sharp and unapologetically bright.

Really like the light. Brightness is impressive and various options are both fun and functional as well as effective. The only downside is the rubber strap that attaches the light to the seat post. Since it is freely removable, it falls off easily and I am certainly going to lose it at some point point. I wish half of it stayed permanently attached to the light
Bright multi mode rear light also visible to side. Only downside was USB-C charger not included.
