BTDT, the pinout is different, but I don't remember exactly. Itrs easy to
figure out...

Again, the reason I tried these is that the lumens/watt is about 20% higher,
and the 55 watt gaves 30-35% more light.

Finally, you need to mill a new grove into the 9007 base so it will fit into
the reflector housing.

You will notice an improvement, the normal driving lights are quite a bit
brighter. The light output pattern does not cut off as sharp as the 9004.
