I've since learnt that the right drivers side lamp dips and angles outward under 40 kmh. I needed help from a friend to send me pictures of how his lights point in reverse gear, neutral and high beam.

The best way is the set height of passenger lamp, and turn on high beam to adjust level and gap between drivers side lamp vs passenger side.

Technically both lamps on high beam should be perpendicular when pointed onto wall - the horizontal position.
