Bike lights

Bike lights let you see the way and be seen by others. For unlit roads and trails, a front light needs enough output and a beam that reaches far; on public roads, a beam with a cut-off avoids dazzling oncoming traffic, and some countries require type-approved lights. Consider battery runtime at your usual setting, USB charging or dynamo power, and mounts that hold securely on your handlebars and seatpost.
