I have had a handlebar light in the past and they work well but with the light mounted on my helmet I can turn my head to look at an object or an automobile off to my side so I am able to quickly to anaylize the situation.
Easily attaches to the helmet to provide a mounting location for a light. The unit itself is light weight. The Velcro works well. As pictured provides round mounting point so a small light, or other light weight device which is designed to be mounted on the handlebars could be attached to the helmet.
