Just guessing but I imagine one is a high beam and one is a low beam.
The standard headlights use one 9004 bulb per side, while the sport headlights use two bulbs, a 9004 and a 9007. Light output is better with the sport headlights. This info is for model years beginning in '94 and '99-01 sport headlights. Retrofitting requires adapting the wiring to the two bulb system and cutting some sheet metal behind the headlights for clearance.

I need help too, but I know you need a 9007 lamp.

If you dont have the bulb from the driver's side, pull the one from the passenger's side, thay are the same. Look at the pastic part of the bulb. There will be a number, either 9004 or 9007. That is an industry standard number that is used across bulb brands. Ford only used either a 9004 or a 9007 bulb in those years. After you have figured out which one you have, go get it.
