FORD 1998 Expedition - Manual (Page 180)

Do not remove lamp bulbs unless they can be replaced immediately with
new ones. If a bulb is removed for an extended period of time,
contaminants may enter the lamp housings and affect lamp performance.
Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully and keep out of
children’s reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
1. Make sure that the headlamp control is in the OFF position.
2. Open the hood.
3. At the back of the headlamp, pull
clips rearward and up (about
3 ⁄
4
inch) to release the headlamp
assembly.
4. Slide headlamp assembly forward
and off of guide ribs to expose the
back of the bulb and wiring
connector.
5. Release clip and disconnect the
electrical connector from the bulb.
6. Remove bulb retainer ring by
turning it counterclockwise about
1 ⁄
4
turn, then slide the ring off the
plastic base.
7. Without turning, carefully pull bulb assembly out of headlamp
assembly.
