Beryl Burner Brake

Burner Brake can detect when you slow down, accurately warning other road users that you are putting your brakes on by intensifying the light. We've also got the basics covered: Burner Brake is a waterproof, 200 lumens rear light with Day Flash mode to keep you extra safe, and fast USB charging.
The Burner Brake is powered by Beryl's bespoke braking algorithm - a smart accelerometer that knows when you're purposefully braking and want to alert road users behind you. No more false alarms.

Choose ‘day flash mode’ for maximum visibility during the day. 200 lumens to keep you visible before and after the sun sets.

Burner Brake can go from zero to half charged in only half an hour. And from zero to full battery in 1 hour and 30 minutes. Minimum charging, maximum enjoyment.
