Ensuring headlights are turned on is crucial for enhancing safety in low visibility conditions. When visibility is reduced due to factors like fog, rain, snow, or even at dawn and dusk, using headlights allows other drivers and pedestrians to see your vehicle more clearly. Headlights illuminate the road ahead and help you notice obstacles or road signs in your path, which is vital for safe navigation.

Driving without lights can lead to dangerous situations, as it greatly reduces your visibility and makes your vehicle less visible to others. Similarly, using high beams in conditions where visibility is already poor can create glare and response challenges for other drivers, potentially causing accidents. Continuously signaling while driving is a good practice for communication with other road users but does not directly enhance visibility in low light situations in the same way that proper use of headlights does. Therefore, turning on headlights is a fundamental step to ensure safety when driving in low visibility conditions.
