Replacing Headlamp Bulbs - Ford 1999 F-350 Owner's Manual

Maintenance and care
• Tail lamps
• Back-up lamps
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 (aerodynamic)
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. Release clip and disconnect the electrical connector from the bulb.
4. Remove bulb retainer ring by
turning it counterclockwise about
turn, then slide the ring off the
plastic base.
5. Without turning, carefully pull bulb out of headlamp assembly.
6. Insert the glass end of the new bulb into the headlamp assembly.
When the grooves in the plastic base are aligned, push the bulb into the
lamp assembly until the plastic base contacts the rear of the lamp
assembly.
7. Install bulb retaining ring over the plastic base and lock the ring into
the socket by turning it clockwise until you feel a "stop."
8. Connect the electrical connector into the rear of the plastic base until
it "snaps."
