When was the last time you changed a headlight bulb Dave ?

I changed the dip pair car recently. H7. They were old and not as bright
as new.

They have
offset locating 'tangs' on them to make sure that the main and dip
filaments are correctly located in the reflector.

Quite.

Unfortunately, many
modern headlamp units are so awkwardly located that bulb replacement
can only be carried out by feel. In these cases, it is perfectly
possible to get the bulb in place such that at least one of the
locating tangs is not in its slot.

It's possible to cross thread a nut too.

Because the retaining clip is only
made of a thin gauge spring steel wire, it is vanishingly easy to force
it back into its clip, thus holding the bulb in its seat at an angle.
The result of this is a beam pointing either at the ditch, or the moon

And you'd leave it like that till the next MOT?
