Burner Brake is a great rear bike light from the team at Beryl. It's bright (200 lumens), waterproof and rechargeable but what sets it apart is the ability to detect when you slow down and warn other road users by intensifying the light.

There's up to 17 hours of runtime, mode dependent, and a full charge is super quick; just 1.5 hours. Choose from a range of modes to best suit the conditions and get excellent 180-degree visibility. Constructed from a carbon grey polymer, the casing is tough and durable and fully waterproof.
