Cars are owned according to its visibility considerations. It is never known for the drivers when the car will face a fog, snow or rain. So it is difficult to drive in rain or fog and makes the drivers confuse in which routes they will go. The use of fog lights is previously under-estimated but recently the use of it has come into focus. Normal lights cannot illuminate a path clearly as they have a limited range of brightness. Normal lights have short wavelengths compared to fog lights which make them less visible in bad weather.
