What is the role of a fog light?

The role of a fog light is specifically designed to improve visibility during foggy or low-light conditions. Fog lights produce a wide, low beam of light that is aimed at the road immediately in front of the vehicle. This helps illuminate the area just ahead without causing glare, which can happen with standard headlights in fog, rain, or snow.

The unique design of fog lights allows them to provide better clarity in situations where low-lying clouds or precipitation interrupt visibility. Their positioning and beam pattern focus the light in a way that reduces the amount of light scattering that occurs when standard headlights hit fog or heavy rain, which improves overall safety during these adverse conditions.
