Perhaps,but don't look for anything significant.That area is in an area of flow attack,so it tends to be held against the body simply from the favorable pressure gradient there.Also,the area 'behind' it is generously radiused,allowing the flow to easily round the corner to the body sides without separation.Any air trapped where the fog lights would be,simply pools there,with the outer,active flow just skimming off it, as though it were solid.
