Exposure BOOST-R 3 REAKT is a powerful, lightweight and intelligent rear light for demanding cycling use. It is well suited for road cycling, gravel, commuting, winter riding and situations where good visibility is an important part of safety.

The maximum output is 200 lumens in flash mode, while constant mode provides up to 75 lumens. Runtime varies between 6 and 70 hours depending on the selected mode. This makes the BOOST-R 3 REAKT a good option for both short rides and longer days on the bike.

One of the most important features of this model is the ReAKT brake light function. The light detects braking and automatically increases brightness, helping riders and vehicles behind you notice changes in speed more easily. In addition, the light adjusts output according to ambient light conditions, improving visibility in changing environments.

Peloton mode is designed especially for group riding. When another cyclist is riding close behind, the light automatically dims to reduce glare. When there is no rider close behind, the light returns to normal visibility. This makes the BOOST-R 3 REAKT a practical choice for group rides as well.

The DayBright beam pattern improves visibility also in daylight. Side visibility helps make the rider easier to detect at intersections and in other traffic situations.

The body is made from anodised 6063 aluminium. IP67 protection provides good resistance against dust and water, making the light suitable for poor weather conditions. USB-C charging makes everyday use simple and modern.
