Illuminated Entry; The Inside Lights Will Not Turn Off If - Ford 1998 E-150 Owner's Manual

Illuminated entry

The interior lamps illuminate when the remote entry system is used to
unlock the door(s) or sound the personal alarm.
The system automatically turns off after 25 seconds or when the ignition
is turned to the START or ACC position. The dome lamp switch (if
equipped) must not be set to the OFF position for the illuminated entry
system to operate.

The inside lights will not turn off if:

they have been turned on with the dimmer control or
any door is open.
The battery saver will shut off the interior lamps 40 minutes after the
ignition has been turned to the OFF position.
