Using low beam headlights during a heavy snowstorm in the daytime is the appropriate choice because they provide adequate illumination without causing excessive glare. Heavy snow can reflect light back at you, and high beams can create a blinding effect as they illuminate the snowflakes falling in front of your vehicle.

Low beams are designed to cast a wider, shorter beam that helps you see the road better without reflecting off the snow in a way that impairs your vision. This setting ensures that you can see and be seen by other drivers more effectively, improving safety for yourself and others on the road.

Fog lights are typically used in conditions of thick fog or heavy rain, but they are not necessary in snow and may not offer the best visibility under those circumstances. Daytime running lights do increase your vehicle's visibility to others but do not provide sufficient illumination for the road ahead in poor weather conditions. Therefore, using low beam headlights is the best option during a heavy snowstorm.
