Does anyone know what this hole by the fog light is for on a 2012 Pilot EX-L 4WD? It is on both sides, driver's and passenge's. I thought It might be for adjusting the aim of the foglights from outside the vehicle. Unfortunately, if it is, I don't know what kind of tool to stick in the hole. I've tried both phillips and straight lade screwdrivers but neither seems to engage anything llke a screw head. A flashlight aimed at the hole isn't any help.
