Exposure Lights Blaze MK3 ReAKT and Peloton Rear Bike Light

The Exposure Lights Blaze MK3 ReAKT and Peloton is a sophisticated rear bicycle light designed to enhance rider safety through intelligent, adaptive illumination. It employs ReAKT (Ambient Kinetic Technology) to automatically adjust its brightness based on surrounding light conditions and can detect when the rider is braking to strengthen its output. This ensures optimal visibility in varying environments, from bright daylight to low-light urban commutes. A dedicated Peloton mode makes it particularly suitable for group riding, as it senses approaching lights from behind and dims to prevent dazzling other cyclists, then brightens when at the back of the group to maintain a strong tail light for all road users. The light features a maximum output of 150 lumens and offers several lighting modes, including a solid beam and various flash patterns. The Optimum Mode Selector simplifies operation to just two primary modes—flashing and solid—for easy switching during a ride. DayFlash mode provides a distinctive double strobe designed to cut through visual clutter on busy roads, significantly improving daytime visibility. Power is supplied via a built-in rechargeable battery, with runtimes ranging from 6 to 48 hours depending on the selected mode. Charging is accomplished through a standard USB cable, with a full charge taking approximately four hours. This light is an excellent choice for cyclists who regularly ride in groups, commute in mixed lighting conditions, or undertake longer adventures where reliable, adaptive lighting is crucial. The included seatpost bracket offers secure mounting, and the overall design prioritises both functionality and rider consideration. Its blend of automated features and user-selectable modes makes it a versatile companion for road cycling, time trials, and extended tours, providing peace of mind through enhanced visibility without requiring constant manual adjustment.
