Using headlights according to lighting regulations is crucial for safety on the road. The primary reason is to enhance visibility during times when natural light is insufficient, such as at night, during inclemency, or in other low-light conditions. This not only allows drivers to see the road and surrounding objects more clearly but also helps them identify the presence of other vehicles from a distance. By having their headlights on, drivers can better navigate potentially hazardous situations, reducing the likelihood of accidents.

While headlights can improve visibility in fog, signaling to other drivers, or even having an aesthetic appeal may be secondary aspects, the fundamental requirement is related to visibility and safety, particularly in conditions where illumination is inadequate. This aligns with the importance of ensuring that all road users can see and react to each other effectively.
