Callisto

Making yourself visible in city traffic can help motorists see you better, and a good helmet mounted light that is worn on your head, up and away from the distraction of car lights, can make you stand out in a sea of vehicles. The Callisto is a headlight and safety light in one unit. Not only can it be helmet mounted but it can also easily be handlebar mounted. Both mounts are included in the box.
