Exposure Lights TraceR MK4 ReAKT Rear Light

Engineered in the UK for discerning commuters, group ride enthusiasts, and all-weather cyclists, the Exposure TraceR Mk4 ReAKT Rear Light redefines rear visibility through intelligent, adaptive technology. Traditional tail lights maintain a fixed output regardless of your riding environment, but the TraceR Mk4 ReAKT actively responds to your movement and surroundings. Delivering up to 200 lumens in a ultra-lightweight 35-gram package, this light features ReAKT technology that automatically flares under deceleration and brightens in strong ambient light, whilst easing off to prevent blinding riders sitting on your wheel. Rapid USB-C charging brings the internal battery to full power in just 90 minutes, making it an effortless addition to daily riding setups.

All-Weather Durability and Complete System Integration

Housed in a rugged CNC-machined aluminium body with an IP67 rating, the TraceR Mk4 ReAKT easily shrugs off relentless road spray, heavy rain, and harsh winter conditions. For complete illumination coverage, it seamlessly pairs with the Trace 4 front light to ensure you remain exceptionally visible from every angle, day or night. Ready to ride straight out of the box, each package includes the TraceR 4 ReAKT light, a secure seatpost bracket, a USB-C charging cable, and a quick-start guide, providing long-term reliability and peace of mind for every journey.
