Depending on the part of the world where you live, all vehicles need fog lights for better visibility. Fog is usually common in the temperate regions which experience winter. The fog lights are meant to illuminate the low lying areas especially during heavy fog. Most of the cars automatically come up with the fog light when they come out from the factory. Normally, the fog lights are installed in the front bumper. However, if you want some more coverage from the fog light, you can always purchase additional set of them. They are also installed at the rear end of a car but they are optional. They are mostly used to indicate the cars coming behind that the visibility is not clear ahead. But you should take extra care before switching on the rear fog lights accidentally as the cars coming behind may stop suddenly and it may cause an accident.
Fog lights create much wider, but at the same time shorter beam of light. It means that your field of vision is now lower to the ground, but a lot broader. Fog lights also cut back the glare in the process. Fog lights even do a better job illuminating the corners when you're turning thanks to the wider beam of light. The fog bulbs of purplish color are also in great use these days as these are very bright too. The color of the fog light plays an important role as different color lights have different capacity to penetrate the fog. Conventionally fog lights color is yellow because it is the only color which posseses the longest wavelength among all visible lights. Yellow color fog lighting reduces dispersion, the light hits and scatters the water vapor. Most fog lamps are spherical in shape and contain simple components.
They not only provide greater visibility but also give your automobile a new shape. There are various shapes of fog lights, and you can actually instruct the manufacturers to make them in the shape that you want. You can also go with your car to the manufacturers and have them suited so that it looks superb. You should consider the design and style of your car too before purchasing a set of lights of certain design and color.
