Hi!
OK, so if you've tried several lights, and all of them have the same problem, then (unless all those lamps are dead) the issue must lie with the car, not the light units.
1) Check that the manual light positioning dial by the steering wheel isn't set in the "low" position
2) Perhaps the light unit is not being positioned properly, so it tilts downwards (missing bracket / bolt, something is stopping it seating properly?)
3) The headlight leveller system is not working, or the cable on that side is unplugged, so the beam on that side is not being adjusted to the correct position
For years my 1.5 had very low headlights, I didn't realise that the cables for the levelling system weren't plugged in. When I plugged them in, the beams adjusted automatically and suddenly I could see more than 6 inches ahead of the car!
Also, are you sure that the problem isn't the left light, i.e., that one is too high? Again, that could indicate a levelling issue on that side.
