Or at least, I think it does:
Key: Battery + to High meant I had the red probe on the battery positive terminal, and the black probe on the bulb leg for the high beam feed.
Battery - to High meant the black probe on the negative terminal, and the red probe on the bulb's ground.
I had an awesome spreadsheet to do the output difference calculations, but suffice to say a low beam at 11.35V is going to be pretty poor...
Maybe I did the whole thing wrong... I thought for some reason I should be seeing readings like -1.2 or something like that. I suppose it would help if I knew the pinout of the 9003 (which should be simple to test with the ohmmeter, you'd think).
I did find this pinout of the socket: http://i51.photobucket.com/albums/f369/bbottomley/Forester/H4pinout.gif
I think I may have been doing it wrong, but now it's too hot outside to go and mess with it again.

In both cases, the heater fan was set to maximum
