Side Visibility When cycling in largely built-up urban areas & dealing with other road users it’s more important than ever to stay visible from multiple different angles. The Click USB (Universal Serial Bus) lights both come with a specially designed light beam that is channelled not only frontwards but also out to the sides for ultimate lighting coverage. Battery Light Indicator To ensure that you never end up in a black out scenario the bike lights both come with individual fuel gauges in the form of tiny LED lights. The light works with a traffic light system to show you the decreasing or increasing nature of your battery life. Green: 100%-75%, Orange: 75%-25%, Red: 25%-0%. USB (Universal Serial Bus) Rechargeable One of the most brilliant thing about this light set is that it is so user friendly & one such feature that helps you even more than ever is that both lights are Micro USB (Universal Serial Bus) rechargeable. Coming with charging cables the lights can both, quickly & easily, be charged via any standard USB (Universal Serial Bus) port. These can be found as part of a large range of devices such as your laptop, computer desktop, or as part of your smartphone charger. Mounting System To fit in with the compact size of this light set the, integrated, mounting systems for both lights have also been designed to be as streamlined as possible. Inspired by the small, sleek nature of action camera mounts the Click set mounts can be fitted to any handlebars or seatposts with a diameter of 22-35mm which covers a large range of different bike frame types.
