When you face moments of increased risk on your commute (e.g. at junctions, filtering traffic, or high-stress intersections), ACE reacts by automatically flashing brighter and faster to make you more visible to other road users. It also shines powerfully both in daylight and at night-time, helps you be seen from over a mile away, and gives you 200° of side visibility.
