Here's a way to avoid the mountains and traffic of Roanoke and enjoy a pleasant ride at the same time. An icy haul up and down Bent Mountain. Not for the faint of heart. Many who ride with a single light prefer a helmet-mounted lamp, which allows the rider to move the light beam without moving the bike's handlebars. Average light outputs range from 6 watts to 20 watts.
Some systems offer adjustable light settings.
A necessity on the road, taillights are also helpful off-road. Because they are designed to be seen, not to help a rider see, the lights aren't as powerful and cost a fraction of the price of headlights. Some batteries are contained in holders shaped like water bottles and are carried in water-bottle cages on a bike frame. Batteries for helmet-mounted lights are carried in a jersey pocket or hydration backpack. Burn times range from an hour to three hours.
