The best-rated bike lights are there to guide you safely through the dark and cold nights of autumn and winter. They are also essential safety features during daylight hours, and many now feature daytime running modes.

Every year, Cycling Weekly seeks out the best bike lights and puts them to the test. This winter, our team tested more than twenty-five of the latest lights, evaluating more than just their brightness. Our main considerations include build quality, battery life, and, by far, the most important factor: how the light beam is projected on the road or trail.
