Some of the posts are misleading as the standard headlamps do not "Auto Adjust". They do not need to adjust as they are already to the legal requirement.
In the Uk you can have (but it is not mandated) a raised part of the dipped beam to the left, to illuminate the footpath and road signs. This would be in the eyes of the oncoming drivers if you took it to Europe.
Yes older cars had a lever to move shutter built into the headlight to blank the raised (UK) bit, or you could put a sticker to blank it yourself.
The modern A-Class has a flat top to the dipped beam making it legal in the UK and Europe, no adjustment needed
The premium lights mentioned above do auto adjust for Motorway/Urban/Roundabouts and the multibeam ones allow you to stay on Main Beam by blanking out the part that would dazzle oncoming driver.

No adjustment needed. It's not because they are LEDs, modern lights are bright enough not to need the extra "kick up" on the Left hand side that we used to have in the UK to improve seeing road signs and pedestrians. On dip beam our lights have the same flat top (cut off) that they have had in europe for a long time.

I don't think there are any bulbs that even the AA man could replace at the side of the road. I was told by a mate that he just keeps his old ones from a previous car so he can show the cops something, even if none of them would fit.
