Exposures Blaze Re AKT Mk 3 is the ultimate all-purpose intelligent rear light. Its output & features make it perfect for commuting, road, & everything in between. The Blazes Ambient Kinetic Technology (Re AKT) enables the light to automatically flare under braking, & when you enter areas of higher ambient light, it creates a contrast in brightness. Updated with Peloton mode for 2019, the Blaze utilises the Re AKT Technology for use in a chain gang by dimming upon the detection of a rider’s front light, preventing a dazzling effect, but flaring up as a beacon at the tail of the pack. Powered by a high capacity battery for substantial burn times, the Blaze Re AKT Mk 3 also features USB (Universal Serial Bus) Charging for your convenience, a choice of 6 burn times & modes, a Day Bright flash pattern for use at both day & night, & side illumination that delivers 180 degrees of visibility.
