What type of headlights are required to be used in foggy conditions?

In foggy conditions, low beam headlights are required because they are designed to provide adequate illumination without causing excessive glare. High beam headlights can create a significant amount of light that reflects off the moisture in the fog, leading to a blinding effect for drivers. This glare reduces visibility and can make it more difficult to see the road ahead.

Low beam headlights, on the other hand, direct light downwards and spread it out in a way that minimizes reflections and maximizes visibility when navigating through fog. This allows drivers to see more clearly while also ensuring that they do not impede the vision of other drivers.

Daytime running lights and parking lights do not provide sufficient illumination for driving in foggy conditions. Daytime running lights are primarily intended to make vehicles more visible during daylight hours, while parking lights are designed to indicate that a car is parked, offering minimal visibility for motion driving.
