best to let a garage adjust head lights because you need equipment to adjust headlights, because you could blind other drivers on coming traffic on the opposite lane causing accident. best let garage adjust headlights wont charge you much.
In the U.S. the type,
adjustments, and illumination factors of all automobile lighting devices
are regulated by the Federal Motor Vehicle Safety Standard 108. The
headlights must function and be adjusted correctly. Your high beams must
disperse their beams straight forward and low beams down and to the
right while safely providing illumination without too much or too little
glare. It is wise to check the headlight adjustment on your Mercedes at
least every year. Doing it yourself will save you time and money. It
will also make driving safer for you and others you may meet on the road
at night. All it takes is time, some basic tools and a little patience.

Remove components if necessary to allow access to the
left/right and up/down adjustment knobs. They are on top of the rear
side of the headlight. The upper knob adjusts the beam to the left and
right. The lower knob controls up/down adjustments.
Park with the passenger side of the car parallel to a solid
fence or wall and about four feet from it. When there is dim light or
darkness, turn on the lights and use your screwdriver to adjust the
up/down knob on the passenger-side headlight until the light beam is
parallel to the ground (you can see the beam of light against the
surface of the wall).
Turn the car so that it faces the wall approximately one car
length away. Adjust the up/down knob on the driver-side headlight until
it is at the same level as the passenger side headlight. Then adjust
both sides until the small groove on top of the beam cutoff is directly
in front of the light.
Reinstall any components that you removed. Close the hood.

The adjustment screws/nuts should be located either on the top of the headlamp assembly,
behind the headlamp assembly, or near the frame rail by the radiator
You will have vertical adjustment screws for each independent beam
(separate highs and separate lows, but will be same screw if highs and
lows are the same bulb). You may also have additional horizontal
adjustment screws as well
your car on a level ground 30 feet from a wall and measure the height
from the ground to the bulb and mark on a wall (do this for highs beams
and low beams if the bulbs are separate, if highs and lows are the same
bulb, only do it for the lows)
For Low Beams: If the headlights read VOR, then
aim the brightest part or cutoff part just below the mark on the wall.
If it says VOL or nothing, aim them 2 inches below the mark on the wall.
For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
two screws on each headlight control the direction the headlights are aimed. One screw, usually at the top but sometimes below the headlight, adjusts the headlight up and down. The other screw, located to one side, controls the headlight from right to left. Turning the appropriate screw one direction or the other will change the direction the headlight points.
In order to aim your headlights you need to have a flat vertical surface you can aim your headlights at in front of a level surface on which to park the car. If your driveway is level your garage door is the perfect place to aim your headlights.
The tools you will need for this job are simple. Masking tape is used to mark where the headlights are to be aimed and a screwdriver is needed to adjust the headlights. A tape measure will be necessary to measure the distance of the vehicle to the surface you're using to check the aim and to measure the up and down distances from your marks.
To start you will want to pull your car quite close to the surface you are using to aim your headlights. This is done to allow you to mark, with the masking tape, where the headlights are on the car. With the car right up against the vertical surface, and your low beam headlights on, the center of the beams will be directly in front of the headlights. Use your masking tape to mark straight across where the headlights are shining. Use short pieces of masking tape to mark vertically the center of the low beams.
, back your car about 25 feet away to check the alignment of the headlights. The brightest spot on your low beams should be about two inches below the masking tape and slightly to the right of the vertical marks. Use the adjustment screws to move the beams up and down, and right and left, until the headlights are aimed properly.
If your car only has two headlights, that's all you need to do. With the high beam lights integrated into the single headlight there is no further adjustment possible. If you have a four-headlight system you will next need to adjust your high beams. Switch to your high beams and adjust them so they shine just below the line and are centered between your two vertical marks.
if you look at the light, there is an adjustment screw at the top of the light that controls the up and down motion , clockwise will raise the beam, and a screw on the side that controls the side to side motion. the best way to center your lights would be to park the vehicle 25 feet away from a verticle wall. be sure to be very square to the wall and on level ground. make a tape line vertically on the wall in very close relation to the center of the vehicle, and another tape line vertically in very close relation to the center of each headlight. now place a tape line horizontally in very close relation to the center of the headlights. start with low beam adjustment. adjust the high intensity zone to 2 inches below the horizontal line and 2 inches to the inside of the vertical line directly in front of the headlight. for high beam adjustment, adjust so that the high intensity zone is centered on the center vertical line and just below the horizontal line. hope this helps
Further to Emmisionwiz's answer that worked for me - the holes are in the black plastic covering the radiator support, to each side more or less in line with the headlights. They are marked with an "A" and rotation directions for UP and DOWN. The Phillips screwdriver goes into the hole about 45 degrees from vertical and engages the adjusting rack, where the teeth of the Phillips screwdriver are the pinion. If you shine a flashlight down the hole you can see the rack teeth and all becomes clear. But you will need a long Phillips screwdriver and a little bit of luck.
In the owner's manual it says the lights are adjusted correctly at the dealership and if they need adjustment because of a trailer then take the car to a Honda certified mechanic.
I have a 2004 Accord also and the method is the same for that one too.
