A6 Quattro/lights

[auditodd at attbi.com]

Just a note on installing halogen headlights. The couple posts I saw mention
cleaning with a towel before installing and DO NOT touch the glass with your
fingers.

I would like to go one better. I always clean the glass portion of the light
with alcohol, even if I didn't touch the glass myself. There is no guarantee
that the people packaging the bulb didn't touch it.

Better safe than sorry.
