I was getting a year of service out of the headlights on my 2000 A4,
changing them one at a time. Usually, the second one would go within a month
of the first.

Two years ago, I changed both at the same time and haven't had to do so
since. I am an electrical engineer and, frankly, I consider this a
coincidence. Unless, of course, either I or someone else can come up with an
explanation that makes logical sense.
