Exposure Boost-R 3 with ReAkt

The BoostR 3 is a compact, high-performance rear light built to maximize visibility for everyday commuting. Designed for cyclists who value safety, convenience, and a streamlined setup, its lightweight construction and sleek profile integrate neatly with any bike.

Now delivering up to 200 lumens in flash mode and 75 lumens in steady mode, the BoostR 3 offers enhanced brightness for greater visibility on the road. Its larger-capacity battery provides up to 70 hours of runtime, making it ideal for daily rides as well as extended cycling adventures. Paired with a precision-engineered lens and the signature DayBright pulse pattern, it helps ensure you're clearly visible in both daylight and low-light conditions.

Equipped with intelligent Reakt technology, the light automatically adjusts its brightness to match changing surroundings. It lowers output in darker environments, such as tunnels, to conserve battery life, then increases brightness again in daylight to maximize visibility. Reakt also incorporates an automatic brake light function, boosting brightness during deceleration to alert riders and motorists behind you in both steady and flashing modes.

For group rides, Peloton mode improves comfort and courtesy by automatically dimming the light when another rider is detected closely behind, then restoring the previous brightness once they move away.

The carefully engineered body and lens design provide excellent side visibility, helping increase your presence in traffic. An 8° collimated spot lens projects a focused beam with impressive long-range visibility, offering greater clarity than many lights with comparable output.

Constructed from precision CNC-machined 6063 aluminum and finished with a durable gunmetal grey anodized coating, the BoostR 3 is built to withstand demanding riding conditions. Its IP67 weatherproof rating ensures dependable performance through rain and harsh weather, while its lightweight 45 g design delivers durability without unnecessary weight.

Combining intelligent lighting technology, extended battery life, and outstanding visibility, the BoostR 3 is designed to help you stay visible, ride confidently, and remain safer on every journey.
