Headlights are an essential part of a vehicle; they illuminate the road and surrounding area when it is dark or when conditions require extra light. Fog lights are very similar and can provide additional light when needed. When is it essential to use headlights, and when would fog lights become beneficial?
The fog light is pretty different than a headlight. As you can tell from the name, it’s actually meant for use when there’s too much fog ahead of you. Usual headlights struggle to pierce through dense fog, especially during winter.
Fog lights can produce a wide beam of sharp light that can cut through the density of fog pretty smoothly.
Fog lights are usually placed right below the headlights and are not used unless quite necessary. It's ideal to use fog light only if there’s dense fog around you and you need it to make sure you don’t get into any trouble getting blinded by it.
