Front headlight unit question

[NotAnotherHill]

Having put it all back together, I was trying the beam adjusters to check if they worked. The left side top corner one did (it moves the beam up and down). However the bottom one for the main beam didn't seem to do anything. It should have moved it left/right but I didn't see any beam movement despite turning the adjuster plenty. It appears to be working when you look at the bolt through the lens but I can't see the reflective lens backing move. Should the left/ right be noticeable?
