it is daylight. why should you turn your headlights on when it is raining?

You should turn your headlights on when it is raining because rain reduces visibility for both you and other drivers. Headlights improve your ability to see the road ahead by illuminating it and help other drivers see your vehicle more easily, reducing the risk of accidents. This is especially important in heavy rain or overcast conditions when natural light is low. Additionally, using headlights in the rain is often a legal requirement in many regions to ensure safety on the roads. Low-beam headlights are recommended to avoid glare that high beams might cause during rain. Turning on headlights when your windshield wipers are active can be a good rule of thumb for safety, making you more visible and helping you react more quickly to hazards.
