Exposure Lights TraceR MK3 ReAKT + Peloton Rear Bike Light

The Exposure Lights TraceR MK3 is an intelligent rear bicycle light designed to enhance rider visibility and safety through adaptive technology. It incorporates ReAKT (Ambient Kinetic Technology), which automatically increases light output during braking and adjusts brightness based on surrounding ambient light conditions. The Peloton mode detects approaching front lights from other cyclists and dims the output to prevent dazzling riders behind, while flaring brighter when you're at the back of a group to alert other road users. This makes it particularly suitable for both solo commuting and group road riding in various lighting conditions. The light emits up to 75 lumens across multiple modes, including a DayBright double strobe that uses full power for low-sun situations. An Optimum Mode Selector allows quick switching between commonly used pulse and steady settings during rides. With an IPX6 waterproof rating, it remains functional in wet weather, and its compact design weighs just 35 grams. The integrated USB-C port provides convenient charging with approximately 4 hours to full capacity, supporting runtimes between 3 and 24 hours depending on the selected mode. This rear light is best suited for cyclists who regularly ride in changing light conditions, from dawn commutes to evening training sessions. Its automatic features reduce the need for manual adjustments while riding, allowing cyclists to focus on the road. The included seatpost bracket offers secure mounting, and the overall durability makes it a reliable choice for year-round use. Whether for urban commuting, road cycling, or group rides, the TraceR MK3 provides a balanced combination of smart technology, visibility, and practical functionality.
