As explained earlier, low beam headlights are used for regular night driving. They also help improve vehicles' visibility in poor weather conditions like rain or fog. Low beam headlamps are angled to focus on the road, considering their short range of illumination. They brighten about 40 meters ahead. Also, low beams are considered the standard and default headlight. The headlamp won't be straining the eyes of motorists or pedestrians as well. Contrasting to many drivers' belief that high beams are meant for extreme weather conditions, it's not.  Low beams are the most suitable to perform this function and better improve vehicle visibility. They help drivers see objects and road lines ahead.
