Not certain whether you want to mount your light on your handlebars or helmet? Not to worry, the Evolution includes both a universal handlebar mount, able to fit oversized bars and a helmet mount. Ease of operation and mounting flexibility make the Evolution a favorite among commuters and offroad enthusiasts alike.
