Fog lights are necessary because regular headlights are simply not safe enough for foggy and raining condition. A headlamp light becomes "backscatter," when light is reflected back by rain/fog to the driver's eye. The backscatter also creates glare, which is defined as light much brighter than the driver's level of dark adaptation. Glare creates visual discomfort and lowers the ability to see. The poor visibility causes people to concentrate their attention directly ahead in order to see where they are going. This would be harder to see a car or pedestrian approaching from the side. Fog is very fine droplets in the air, so the amount of scattering is even larger and there is more loss of contrast and more backscatter from headlights. This is the reason that you should not use high beams in fog. Fog lights work by capitalizing on the basic principle, "angle of incidence equals angle of reflection." They are mounted low and project light directly along the road. As a result, there is little scatter back to the eye.
