Driving with only your parking lights on is considered illegal and unsafe because parking lights are specifically designed to indicate that a vehicle is parked and not in motion. In low visibility conditions, such as during rain, fog, or at night, relying solely on parking lights does not provide adequate illumination for the driver or visibility for other drivers on the road.

Using headlights is essential for ensuring that you can see the road clearly and that other drivers can see you. Headlights are designed to shine brightly enough to illuminate the roadway and enhance the driver's ability to see potential hazards. Therefore, driving with only parking lights compromises safety and does not comply with traffic laws. This is why it is important to always use appropriate headlights in any driving situation that requires them.
