The LOOP-100 is a compact, feature-packed taillight built around a precision CNC aluminium housing that weighs just 25g. The smart brake sensor automatically boosts brightness to 100 lumens when braking is detected, then drops back to the previous mode — working across all seven light modes. A vibration sensor puts the light to sleep after 120 seconds of inactivity and wakes it when motion resumes, helping stretch the battery to up to 40 hours runtime.
