Hi Leeroy
What i do is have the car on a flat surface with it about 8 metres from a wall or door and and have the beam the same height of the ground as the lights are on the car and if you have a centre line marked on the wall i use masking tape and have them the same distance apart on the wall as they are on the car
Its alot easier to do this when its abit dark

Regards
Paul
