HI Shane,
Your bulb type is
2002 FORD Expedition
High & low beam headlamp
9007
You have two choices for the 9007 (hi/lo and bi-xenon)
hi/lo means your low beam is HID and high beam is Halogen because this bulb type has two bulbs in one bulb base to go from low to high beam.
And the bi-xenon means both your low and high beams will be HID.
Here is the link to your 9007 hi/lo 6000K ($60 after coupon code from first page of the thread or on the signature)

All plug and play no cutting or splicing required, Thanks~
