In autumn, a ride home can begin in daylight and end in darkness. Start choosing bicycle lights by thinking about the route you actually ride. On a well-lit city street, a front light mainly helps others see you; on an unlit road, it also needs to illuminate the surface far enough ahead.
If one set of lights serves both town and countryside, adjustable brightness is useful. Aim a strong beam lower in the city so it does not dazzle approaching riders or drivers. A steady light can help others judge distance, while a flashing light attracts attention; some riders use both.
Before setting off, check that both front and rear lights are secure and charged. Reflective details on clothing or a bag can add visibility, but they do not replace the lights themselves. If your routes vary, describe where and how long you ride after dark when asking a cycle shop for advice.
