Basically, we have 5 types of light patterns: Fog, driving, spot, flood and combo?

Fog: Fog lights provide a low, wide-angle light pattern to increase short-range visibility. Both amber and clear fog lights are suitable. Amber, while not penetrating, is more visible to approaching vehicles. They are intended to be mounted below the headlights and project a beam pattern which is very wide but not very tall or far. This pattern lights up a pathway close to the ground but does not light the airborne particles in the line of sight – this increases the visibility in bad weather. Auxbeam Fog Lights are very useful in Dust, Fog, Rain and Snow. They also work well as Cornering lights in clear conditions.
