If you look in your owners manual there are step by step instructions on how to properly change the headlight bulbs in your truck.
According to the 2001 Ford F-150 Owner Guide : Each headlight has ( 1) # 9007 bulb
blinker blubs on a 1997 f150 front blubs
The headlight adjustment for the 1989 F150 2WD is below the actual headlight. You will need to pull the tab at the top of the headlight up to release the headlight and then you can adjust the angle of the light with the long bolt below the housing.

Changing F-150 Headlight BulbsI'm not familiar with your 2004, but I drive "89, and '93 F-150s.My headlight bulbs are inserted into a lamp-holder that mounts into the back of the headlamp assemblies via a 1/4 turn locking "tab" method.To remove the lamp-holder I just turn it one quarter turn counterclockwise, and pull it toward the rear of the vehicle. It is not even necessary to remove the wiring harness/connector from the lampholder.
