Where are the adjusting screws on the headlights of 2007 Chevy Silverado new style truck?

Adjusting Silverado Headlights
1 Open the hood and look directly down onto the top of the headlight to be adjusted. Just above the headlight housing will be a white Teflon or plastic screw. This adjustment screw will adjust the headlamps up or down, depending on the direction the screw is turned.
2 Adjust the screw clockwise using the Phillips screwdriver to rotate the light beam up to the desired angle.
3 Adjust the screw counterclockwise using the Phillips screwdriver to adjust the light beam down to the desired angle.
4 Adjust the white Teflon screw on the second headlamp in the same direction as needed to level the beam to match the first headlight beam.
5 Verify the proper angle has been obtained by pulling the vehicle up to a wall or garage door with the headlights turned on. If light beams do not appear level with one another, repeat adjustment until desired angle is obtained.
