Gransport headlamp height adjustment - Halogen

[Yorkshire-Trident]

I'm trying to adjust the headlamp height on my gransport after it failed an MOT for being set too high.

I have tried to find on other threads the adjustment, but they seem to refer to the Xenon lights. That adjustment screw is not visible to me.

I know the knob adjusts horizontally. Can someone point to the vertical adjustment in this image for me please?

This is the LH light
