KNOW WHY FOG LIGHTS ARE USED !!

Front-facing fog lights and fog lamps are a type of automotive headlight that is designed to emit light in a bar-shaped beam. The beam is typically designed to have a sharp cutoff on top, and the actual lights are usually installed low and aimed toward the ground at a sharp angle.

WHY DO WE NEED THEM?

Fog is a regular occurrence in many parts of the world, especially near large bodies of water. When the conditions are right, tiny water droplets or ice crystals can float in the air, just over the surface of the ground. In addition to acting like a cloud and blocking your view, the tiny water droplets or ice crystals decrease visibility even further by reflecting light that hits them. This makes driving through fog with headlights, and especially high beams, a frustrating and dangerous experience.

Fog lights are a solution here, and take a different approach to all that water vapor hanging over the road. They work in multiple poor visibility conditions, including fog, mist, snow, and even blowing sand. In order to let you see the road through the fog, factory-equipped fog lights are placed as low as reasonably possible, usually in the lower bumper cover on most modern vehicles.

The purpose of the fog lamp is to show the driver the road edges, lane markings and the foreground abruptly appearing during road drive. When used with headlamps in extremely poor visibility, a driver can maneuver safely at slow speed in snow, fog or heavy rains.

DIFFERENCE BETWEEN HEADLIGHT AND FOG LIGHT

1.Driving lights are used in vehicle to provide clear view of forward of the vehicle and intended to supplement the high beam of a standard headlight system. While fog lights are used to reflect the fog, snow, or dust particles in the air are developed for use on dangerously thick conditions.

2.Driving lights produces white light while fog light produces both white and yellow light.

3.Driving lights are used to show clear vision to avoid any road obstacles during night time while fog lights are used in specific conditions like dust, train, fog or snow.

4.Driving lights are installed in every vehicle by default by the manufacturer while in some areas fog lights are also installed according to weather condition in specific region and in most areas it is optional.

WHEN TO USE FOG LIGHT:

You should only use fog lights in situations where there is poor visibility conditions caused by rain, fog, snow, or even an excessive amount of dust in the air.

In short, we can say that fog lamps should be only used in conditions where there is less visibility caused due to snow,fog,dust or rain.We should not use fog lamp in clear conditions as it may distract other drivers on road.
