The uvex exxential II LED is the perfect helmet for riders who wish to be fully prepared for an outing in the evening hours. Although the passive helmet lamps are no replacement for a headlamp that lights up the route, it does significantly increase the rider's visibility in the twilight and enhances safety in general. Three lighting modes are available as required: constant, flashing and pulsating. A plug-in LED with a magnetic holder at the rear controls the system. This functions as an additional rear light and also contains the battery level display. Depending on the mode, one charge will last between 6 and 12 hours. The very lightweight inmould helmet also impresses with its ergonomic design and a deeper-cut section at the rear. Adjustment in height and width with millimetre precision is possible by means of the 3D IAS system. The ventilation system ensures a perfect climate inside the helmet.
