I'm having trouble with the headlights on my 2011 Pre Runner. Right from the factory they were a little high, and with anything at all in the box it's even worse. The dealer says there is no adjustment, and I cannot see any adjustment screws. Looking on one of these posts, I see an explanation on how to adjust, but on my truck, there are no screws where the picture says they should be. What's up? There must be a way to adjust these lights! Help please.
