They are 9004's, a horrible bulb.

OK, here's the deal.  You know why the sky is blue?  because shorter
wavelengths are diffused more than longer ones (red, yellow) in our
atmosphere.  In other words, "bluish" headlights are tougher on oncoming
traffic, and less useful to the driver.

Also, the shorter wavelengths cause the pupil to contract more than longer
ones (hence the red illumination on most really cool Audi dashboards).  This
is a double assault on the road, doing nobody any good (except for the
"cool" factor, which ain't always cool).

Without exact figures, keep in mind that simple replacement OEM headlights
cost as much as Euro headlights.  And the euro ones are what Audi designed
for the car.

The H4 bulb in an appropriate lens is a wonderful low beam - it has a sharp
cutoff that keeps the light on the road and out of other people's eyes, and
still has a very nice high beam pattern.

Not as badly as you might think, since the HD lights usually also have a
sharp cutoff (no glare except on bumps and odd hills) and might even have a
levelling device in them to minimize the problem further.  But they cost a
lot more than the euro-spec lenses for your car and would be a lot more
trouble to install.  If you can even get them.

One answer, one answer, one answer (ok, I've been listening to too much talk
radio, now that it is 24/7 on airamericaradio.com!).

One answer.  Get the headlight that was designed for your car, the Euro
version, and wire them so they are powered via relays directly from the
alternator or battery jump post.  Nice harnesses that need very little
modification can be had from a number of sources these days.
