The problem is not the replacing of bulbs.
It is the soft suspension of modern cars neccesitating headlight
adjusters that work from the dashboard which some people don't bother
with.


Headlights that are a bit high - maybe. Headlights straight in my face
or right in my mirror - moron behind the wheel who doesn't know what a
blue warning indicator means. One headlight in the ditch and one
pointing at the moon - wrongly fitted bulbs. By far the vast majority
of cases fall into the latter two categories, and the problem with the
second of those two most definitely *is* in the replacing of the bulbs ...

4/4s often have headlights mounted such that they shine directly on your
wing mirrors when following closely.
