To Install The New Bulb; Bulb Specifications - Ford Explorer 1998 Owner's Manual

Maintenance and care
5. Remove the old bulb from its socket by gently pulling it straight back
out of the socket. Do not turn the bulb while removing it.

To install the new bulb:

1. With the flat side of the bulb's
plastic base facing upward, insert
the glass end of the bulb into the
socket. You may need to turn the
bulb left or right to line up the
grooves in the plastic base with the
tabs in the socket. When the
grooves are aligned, push the bulb
into the socket until the plastic base
contacts the rear of the socket.
2. Slip the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating it clockwise until you feel a ''stop''.
3. Push the electrical connector into the rear of the plastic base until it
snaps, locking it into position.
4. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
