Its really easy mate, i did mine a few nights ago.
Open your bonnet and look at the headlight. At the back of the lights there are 4x adjustment screws (2 for main, and 2 for dipped beams). Ust an 8mm ratchet spanner if you have one available.
The top screws adjust the high/low position, and the bottom ones do the left/right position. Once you've had a go and think their in a decent position, go for a short drive and all will become clear!
I havent got any pics of the lights to show where the screws are, but will get some tomorrow if you cant find them. Once you've sussed it, it will take a couple of minutes to do, and it looks so much better at night when their adjusted properly.
