Re: Adjusting the headlights on a Mercerdes Benz ML280...
In theory, the headlights are adjusted forward, and centered . so no matter where you drive the illumination should be the same. but there are adjustment screws on all vehicles. so i would say yes, if needed. the lights can be adjusted opposite with the turn of a screw
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The head lights need to be adjusted for driving on the RHS of the road in France. There is no switch to automatically reaim the headlights. You need to take your vehicle to an auto electrican to get the lights adjusted and on your return you need to get them adjusted again for driving on LHS of the road.
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.
Tips & Warnings
This is method is generic for Mercedes models. Some may differ, as there are many models out there.
LOCATE ADJUSTING SCREWS, AND THE BEST WAY TO SET THEM IS A FLAT ROAD AT NIGHT, WITH A DARK BEACH TOWEL, PLACE IT OVER ONE OF THE HEADLIGHTS AND ADJUST THE OTHER ONE. REMEMBER TO AIM THE DRIVERS SIDE JUST TO THE RIGHT, TO AVOID BLINDING ONCOMING DRIVERS.. THIS IS HOW I HAVE BEEN DOING IT FOR 30 YEARS OR SO, AND MAKES FOR THE BEST VISITABLY POSSIBLE !! JAY
There is a conflict with your vehicle and the listing you made for the type of vehicle. But several things to point out. First, if you drive on the opposite side of the road in France versus the United States, the headlight aim would be reversed.
The aim of the headlights can be different in the United States depending on State rules. In general, the curbside light is adjusted higher and the light on the oncoming traffic side is lower. The traffic side is adjusted more towards the center of the vehicle and the curbside is slightly over the curb. You do not want a dark area in the middle of your travel direction.
The vehicle is between 25 and 30 feet from a flat surface The light is adjusted a certain height from the ground. These specs vary and the height of your lights can come into play. Cover the opposite headlight to isolate the beam from the one you are adjusting. A simple towel can cover a lens.
some of these vehicles have a lever on the back where the bulb is that adjusts the shroud in front of the bulb ,but as so many cars get permantly shipped abroad that they dont do it now so you have to buy dealer only headlights
open the hood, take a close look at your headlights, if it is a headlight assembly, there are two screws with big plastic heads on the back of the assembly, these are the adjusting screws. one for horizontal adjustment and the other one is for vertical adjustment.
if the headlight is a round or square ordinary bulb, the adjusting screws are located near the bulb itself, these are philips screws. one on the top and one on the side.
a suggestion; when adjusting headlights, face the car to a wall about 5 ft away and adjust the headlight.
The headlamps themselves will look identical. If you were to look at the beam pattern of the light, then it would be different. Your original headlights were designed to throw excess light to the passenger side of the road (I.E. away from oncoming cars). Now that driving directions are opposite in France, your old headlights would be throwing the excess light into the oncoming cars, blinding them). The new lights are designed to throw the light away from those oncoming cars.
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.
