How do i change the headlight on a 2001 ford escape?

It's a halogen bulb. Just unplug the wires from the bulb. Then there is a locking ring that holds the bulb in. Just turn it to the left and it will come off. Pull the bulb out. They have o-rings on them and sometimes stick in the plastic housing. May have to tug on it a bit.How do i change the headlight on a 2001 ford escape?Pop up the hood. Behind the headlight were the wire is attached is a collar that holds the bulb inside. Turn the collar counterclockwise and pull it out.
