Thanks Anders,
Yes, both high and low beam are pointing close to the car.
I don't know about the bulbs, but as they're separate and it's both high and low beams that are affected, I'm thinking that something else has been fitted the wrong way.
Adjustment mechanism is working just fine.
I know these things can be so easy to get wrong... Typically these things have an adjuster bolt and one doesn't know if the attachment to the adjustment should go in front or behind,...
Ahwell, I'm sure it gets fixed...
