As its name suggests, fog light helps

visibility in the fog. Actually these lights are used in car and truck for safe

driving. This light is a must have for anyone to drive safely in the night. It

can also be helpful to drive against heavy rain, fog or snow. By using this

light the driver can easily view behind or in fronts because they are much

brighter or sharper than the regular flood light of cars. This is even more forceful

than brake light.

Color of fog

light plays an important role to have most advantage from them. Different

colors light have different capacity to penetrate the fog. Usually yellow color

is used in fog light. It reduces dispersion as the light hits the water vapor

and scatters in different directions. It has the longest wavelength of visible

light next to red color. As red color has more penetrating power it could have

been chosen. It penetrates faster than that of other colors. It has more visibility

power in mist or fog from a longer distance than other colors. However, red is

usually used in traffic to show a stop signal, and there are red tail lights. Always

using the same color may look odd. Making use of the same color everywhere may

lead to common confusion. Therefore a yellow color was taken into

consideration. Because it is a bright color and it has more penetration power.

For that reason yellow is generally used. Fog lights of purplish color are also

in use these days as these are very bright.  

Fog light is used in front

of the vehicle. One can get a variety of fog lights offered in the market. These

lights are sold by car aftermarket products vendors, who also sell popular

products such as car body kits.
