There are 2 elements in Headlights ,one for dip and one for main beam so yes "half" the bulb can be broke.
I am pretty sure you have a dynamo and not an alternator.
Your switch appears to be used on UK export models only

I see. The lights stopped working on high-beam aswell the other day, changed the relays just to be sure nothing was wrong there, didn't help. Changed the all the bulbs today and that did not work either..
There is a clicking sound when i switch the high-beam so the signal gets sent somewhere atleast.
So at the moment all lights except for headlights and extra lights work.
Also the ignition switch is changed and working fine now and the car hasn't died like it did before... Yet
