At the top of each light, there's a sort of reversed castellated nut. Basically you stick a Phillips screwdriver into the castellations and turning it moves the light up or down.
A "simple" DIY test is park the car on absolutely flat ground facing a wall, garage door whatever exactly 3 metres away from the headlights.
