At night, visibility can be reduced and it is important for bicyclists to be seen by other drivers on the road. The white headlight helps increase visibility for the rider and alerts drivers of their presence. A headlight visible for 100 feet (Option A) may not provide sufficient time for drivers to react and avoid a potential accident. Similarly, a headlight visible for 200 feet (Option B) may not give enough time for drivers to slow down or stop. Although 300 feet (Option C) may seem like a sufficient distance, it is recommended for bicycles to have a headlight visible for at least 500 feet (Option D) to ensure the safety of both the rider and other drivers on the road. Therefore, option D is the correct answer.
