Low or dipped beam headlight is the projection of light in a lateral or downward pattern. Whether it is rainy, foggy or snowy, low beam headlights should be power on when the visibility is less than 150 meters, even at the time of daylight.

At night, low beam headlights are best used while driving in traffic or in city areas . Yet high beam headlight are for nighttime use in empty areas when no other vehicles are present or coming, because high beam headlight's light is more centralized, allowing you seeing further road, yet they also cause much glare for other drivers. So they are primary used in a poor visibility areas. But never switch to high beam in foggy, rainy or snowy days if there are vehicles around you, because the water molecules reflect the light from the high beam headlights, then in turn, would make it more difficult for other drivers to see clearly of the road.

Yet for a vehicle, it may come with single beam headlight bulbs that means the high beam and low beam are separate bulbs(total 4 headlight bulbs), but it also may come with dual beam headlight, that means high and low beam bulbs are the same bulbs (total 2 headlight bulbs) , and for some Trucks, like for many F-250 F-350 series, etc, even though one bulb has dual function high and low beam, but it has 2 headlight bulbs per side, so still require 4 headlight bulbs.
