It's fairly easy to allign yer lights.
Get a big bit of card board (like a fridge box from the back of Harvey Norman or something) flaten it, and use a marker to draw an even + shape on it.
Park the car on level ground in front of a wall or someplace where you can hang the cardboard level and square. Multi level Concrete carparks are good. Use a tape measure to verify the heights are the same to the bottom of each headlight just incase it's not the lights that are out of whack eg tyre pressure or suspension.
Park the car one or two metres back from the cardboard and turn the lights on, you should immediately see if one light is higher.
Before you play with screw drivers, use a white paint pen to mark the current positions.
To adjust headlights on some cars you first need to loosen all of the retaining screws slightly, then changing the angle with the adjustment screws will have better results.
