Ghostmax suggested it earlier in this thread, that some other applications undergoing the 9004 -> 9007 conversion had done it with an improved beam pattern and more low-beam output.

Presumably, one would swap the low and high beam connectors when performing the 9007 "upside down flip". I tried it briefly, but didn't have it in my to do the major re-aim that would have been necessary to make it work at the time, but maybe I'll play with it a little bit more.
Just wondering if anyone else with a 3rd gen max has tried the upside down 9007 configuration, and if so what did you think.
[edit: whoops I meant 9007, not 8007.]
