Using headlights from sunset to sunrise and during low visibility is essential for ensuring road safety. Headlights serve multiple purposes beyond just illuminating the road ahead at night. They make vehicles more visible to other drivers, which is crucial in low-light conditions such as dawn, dusk, fog, rain, or snow. During these times, visibility can be significantly reduced, making headlights vital for both the driver to see and for others on the road to spot the vehicle.

In contrast, relying solely on headlights for night driving (as suggested by one of the other choices) ignores the need for using headlights in other scenarios of poor visibility throughout the day. The same goes for heavy rain or highway driving, which do not encompass all necessary situations. Overall, the practice of using headlights as outlined in the correct choice supports not only the driver's visibility but also the safety of all road users.
