Exposure Lights Trace & TraceR Reakt Mk4 Light Set Designed and manufactured in the UK for commuters, road riders, and endurance cyclists seeking total illumination, the Exposure Trace and TraceR ReAKT Mk4 Light Set delivers a complete front and rear safety solution in a combined 70-gram package. Pairing a punchy 360-lumens front light with an adaptive 200-lumens rear unit, this system offers maximum visibility without adding bulk to your cockpit or seatpost. Both lights feature fast USB-C charging that restores full battery power in just 90 minutes, making this set the ideal grab-and-go setup for busy weekly commutes and longer weekend rides alike. Smart Illumination and Adaptive Braking Technology The Trace front light casts a bright, reliable beam to ensure you see and are seen through dense urban traffic, while the TraceR ReAKT rear light actively responds to your riding environment. Utilizing ReAKT technology, the rear light automatically flares under braking and brightens in strong ambient light, then eases off to avoid dazzling cyclists riding on your wheel. Together, both units provide comprehensive 360-degree coverage, keeping you exceptionally visible from all angles whether riding in bright sunlight, twilight, or total darkness. Rugged All-Weather Construction and Easy Mounting Crafted from premium CNC-machined aluminium, both light bodies boast an IP67 waterproof rating designed to withstand torrential rain, road spray, and harsh winter conditions. The durable build guarantees long-term performance across every season, while the lightweight form factor easily slips into a jersey pocket when parked. Out of the box, the set includes the Trace 4 front light, TraceR 4 ReAKT rear light, handlebar mount, seatpost mount, two USB-C charging cables, and quick-start guides, offering a seamless setup straight out of the box.
