I used a headlight adjuster at work and measured them up against the headlights and adjusted them accordingly. Your local toyota dealer should have one of these headlight adjusters.
Behind the headlights, there are 2 screws, one more so to the side. 1 of them adjusts the up and down, and the other adjusts the left and right.
I found that you need to do both with a lifted hilux as the up and down one only goes so far, and somehow the other one after adjusted, helps you lift it the little bit more......
hope that makes sense?
If not just take it to the dealer and they should do it, it'd only take 5-10mins to do it right, thats if they know what they are doing.
Oh, by the way, if your headlights are bothering anyone and they are out of wack, when the oncoming traffic high beams ya, just make sure those 240XGT's are aimed correctly so you can blind the hell out of them...
That'd make em think twice
