I did mine as per the thread instructions, I set the lux up about 2 metres from the garage wall put some marks on the wall where my lights hit it and then wound the outside adjustment screws with I think a 10mm socket approx six turns, it is not that obvious that it is moving unless you have a reference point on the wall but it definately works. I did not touch the side adjustment as it seems fine.
I have not been flashed from other drivers for my headlights since
On the internet you can be anything you want. It is strange that so many people choose to be stupid!
