Yes, the reason I mentioned " OFF ROAD " is because the beam pattern changes.

With the filament coil axis left to right, the beam pattern would TEND to 
disperse left to right as compared to a point source. Now, with the filament
coil axis going front to back, the light would start to disperse in all
directions evenly, i.e. sideways, and top to bottom.
The length of the filament is only about 5 or 6 mm, so the dispersion is very
small, the only way to know for sure is to try it.

Guess I'll volunteer, but I may not be able to do it for a while. ( soccer
practice this evening, game tomorrow, then drive to Toronto, ...  well,
perhaps I could use the new lamps on the way back Sunday night, ...
I guess it really is'nt OFF ROAD .....)

The Audi wiring is MARGINAL for 60 watts, you may be asking for trouble 
to go upto 80 watts without at least beefing up the wires. ( just my opinion,
probably not shared by certain Audi engineers ).
