I am not sure where exactly it is. If you look under the hood there should be a screw going down and one near it going sideways. They will probably be near the lights and be sticking out quite far. If you find something like that turn it some and see if it adjust the lights. You may have to take them out the find it. I am not sure though, but I will get back to you.
It's a pain in the ass. Look directly down from above the light with the hood open. You should see a toothed gear looking piece at the back of the light assembly is a cone shaped hole. You will need a long flat head screwdriver to reach in there and turn it. This adjusts the up and down angle of the light. For side to side there is a normal phillips head screw adjustment on the inside edge of the light housing.
