Trace & TraceR Reakt Mk3 Tail Light

The Trace and TraceR Reakt Mk3 light set runs on Exposure's ReAKT logic, an ambient kinetic sensor in the taillight that reads deceleration and surrounding light rather than running a fixed pulse. Braking or riding under a bridge pushes output from 75 to 120 lumens, then it drops back down once the trigger clears. The Trace headlight carries the same daylight-visibility principle through DayBright, a pulse pattern tuned for contrast in full sun rather than darkness. Both lights share identical 57mm by 28mm anodized aluminum housings, so the electronics differ, but the physical platform doesn't.

What Our Gearhead® Experts Are Saying:

"The sensor logic is the part worth paying for. I've run fixed-pulse lights that either blast constant brightness or do nothing until I manually flip a mode, and this one adjusts to what's actually happening on the road."
