Cateye Sync Kinetic 40/50 LM Rear Light

Designed to keep you safer on every ride, the Cateye Sync Kinetic rear light automatically boosts its brightness when you slow down, giving drivers and other road users a clear warning that you are decelerating. Its built-in accelerometer detects changes in speed and instantly switches between two light output modes: a steady 40 lumens for normal riding and a brighter 50 lumens when you brake. This intelligent response makes you more conspicuous exactly when it matters most, helping to prevent rear-end collisions. The light is part of the Cateye Sync ecosystem, meaning it can wirelessly connect to other compatible Sync lights for a coordinated, attention-grabbing pattern. Whether you are commuting in town or enjoying a leisure ride, this compact rear light delivers peace of mind without compromising on battery life or ease of use.
