I know another forum member Vince and myself removed our fog light covers. Well when I was reaching up from under the vehicle to undo the top screw holding the fog light blanking plate , I accidentally started to backout a screw that appears to be related to the headlight assembly. Fortunately I didn't back it all the way out, but when I'm not sure if it's just paranoia or not, I found myself tightening the screw with much more turns as I did to loosen it. Would anyone know what the lower screw on the headlight is for? Hopefully it wasn't an adjustment that I inadvertently over tightened? Pics attached.
All the adjustment screws are on the top of the headlamps, I reckon that one is just a holding screw.
