What is the primary purpose of car headlights?

The primary purpose of car headlights is to help drivers see the road at night. Headlights illuminate the road ahead, allowing for better visibility in low-light conditions. This is essential for safe driving, as it enables drivers to identify obstacles, other vehicles, and road signs that may be difficult to see without additional light. Proper illumination reduces the risk of accidents and enhances overall safety during nighttime driving. While headlights can serve other functions, such as signaling to other drivers or enhancing visibility for parking, their main role is focused on providing adequate light for safe navigation on the road at night.
