What type of headlights are recommended for use in heavy fog?

Using low-beam headlights in heavy fog is recommended because they provide better visibility without causing glare. High-beam headlights can actually make visibility worse in foggy conditions, as the light reflects off the water droplets in the fog, creating a blinding effect for the driver. Low-beam headlights, on the other hand, cast light closer to the ground, reducing reflections and helping the driver see the road more clearly.

Parking lights are not adequate for driving in fog as they do not provide sufficient illumination, and emergency lights are designed for signaling or alerting other drivers rather than for improving visibility on the road. Therefore, low-beam headlights are the safest and most effective choice for navigating through heavy fog.
