It is quite simple to adjust the headlamps vertically. It is much easier that it was searching for someone with an answer on how to do so. When inspecting the headlamps on the 2006-07 you find on the back of the headlamp housing what looks like a cog, or sprocket of a gear, with a vinyl nut on the back of this cog. (I might guess that this is the same 8mm nut used for adjusting the light on the 2005 and earlier models) Above the cog you will see a slot that looks like it would house a #2 or #3 philips head screw driver. IT DOES! Slide the screw driver (at least 6 inches long) into this slot and into the cogs. The screw driver acts as a gear connecting to the other cog. When you turn the screw driver, it turns the cogs and ADJUSTS the headlights! Genius! Good luck. See pictures.
