Dipped beam horizontal alignment.

Anybody know how to adjust the dipped beam horizontally?
The vertical alignment is fairly obvious with the white screw at the back of the headlamp, but the horizontal adjustment is not so obvious.

There is another white adjuster accesed through a hole in the top of the wing, have a snoop around. I think it is the 2nd back of two holes

Thought that was the main beam adjuster, but I'll give it a go.
