Volvo Repair: 2005 S40 Headlight adjustment, xenon lamps, halogen lamps

Question
I am in the military and took delivery of my 2005 S40 in England. Because the car is driven on the left hand side of the road the vehicle requires a light conversion.  Usually they place stickers on the lense to block the light that will blind oncoming trafic.  When I picked up my car there were no stickers and I assumed they adjusted the lights themselves.  When I first drove in the dark I notice that my left light pointed downwards and shines roughly 25 feet in front of the car.  The right light is a little better but is still low.  On a pitch black (Mostly what an English night is like) road I cannot see more than 40 feet and there is no light projected high enough to read signs until I'm almost past them.  I looked at the headlight assembly and found a allen screw with a plastic lock that I assume will adjust the height?  Is this correct or do I need to be looking for something else?  I don't want to go in blind and make this worse or break the plastic assembly.

Thanks for any help you can give!!  

Answer
With this assembly it is very easy to adjust.  The first step is to remove the lens from the car.  on the top of the light near where it meets the fender there will be a slide that goes down into the headlamp that holds it in.  It will look like an upsidedown "L".  Pull that up and out and then the headlamp assembly will pull forward and out.  Once out look at the back of the housing at the back of the reflective element.  There will be one of two things there.  If you have Halogen lamps there will be a sliding tab near the bottom that will go side to side to adjust the reflector angle.  If you have the Bi-xenon lamps, near the side there will be a sliding tab that moves up or down to angle the xenon lens.  Either way unless you have trouble finding the things I mentioned It should take no more than 5 minutes to pull one light out adjust it and put it back.  However you may have to do it several times before you get the desired beam length.  Good luck.  Hope that helps.
