I do not think that the compromise is in the headlamp reflector
design. There is a GREAT voltage drop between the floating
battery voltage ( should be 14.1 volts, but the great Audi
engineers seem to prefer 13.x ) and what the headlamps see.
Before I put relays in, this was ( if I remember ) 0.6 - 0.7
volts.

If you put in higher power lamps without a relay, you might
end up with less light ( due to the higher voltage drops.

You might also end up with "fried" sockets... ( 100/80watts lamps)

Once you put the relay in, its a lot better even with stock
9004 lamps
