Find a flat surface with a wall. Arrange the car perpendicular 1-2 feet or closer from the wall. Make sure it's as perpendicular as you can get it. Turn the headlights on. Mark the hot spots from the headlights on the wall with tape. Back straight up around 5-6 feet or so and note the location of the new hot spots compared to the taped sections. Align the beams until they match. Turn the high beams on and make sure they are even. You can double check it by backing up another 5 feet to see if they are accurate from a farther distance. Done.
