I have done a little 'how to' on adjusting rallye headlights..
Firstly check that you have them set either to RHD or LHD.
This can be changed by slackening the three screws marked here in Yellow, and rotating the projector housing.
This is marked L/S and R/S, this is referring to what side of the road the car is being driven on, not what hand drive it is!
It will probably be easier to remove the headlight to do this, they are only held in with four screws.
Then the actual beam adjustment.
This is done by turning the adjusters marked here in this pic, the red arrows are dipped beam adjustment, one up and down, one left and right (not sure which is which, have to turn one and see which way the beam moves!)
The green arrows are for main beam adjustment.
Dippeds beam are easy, just turn the thumbwheels by hand. Main beam can be adjusted through the slam panel with a suitably sized phillips screwdriver.
pics explain all..

Hope this is of help!!
