fog light adjustment

hey peeps... how do you adjust the fog lights on my 2012 so they shine up a little further?
i know that fogs are supposed to be low, and wide, and not shoot out far, but my truck seems to be shining down pretty low. it apears that the cut off point of light from them is about 3 ft in front of the bumper

 

If you look behind the bumper where the fogs are there is a plastic adjustment knob at the bottom. It has a screw in it that you turn with a Philips screwdriver.I believe turning clockwise should cause them to aim higher.

 

thanks. i just adjusted them... there is a place for a screwdriver, or just use your fingers... it wasnt a tight turn.
