1998 LINCOLN MARK VIII Owners Manual

²Backup lamps
²License plate lamp
Do not remove lamp bulbs unless they will be replaced immediately. If a
bulb is removed for an extended period of time, contaminants may enter
the lamp housings and affect performance.
Replacing headlamp bulbs
The high beam headlamps on your vehicle use halogen bulbs. If the lamp
burns out, simply replace it with a new one.
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.
Unlike the high beam headlamps, the low beam headlamps on your
vehicle use a ªhigh intensity dischargeº source. These lamps operate at a
high voltage.
Low beam headlamps that flicker, are dim, or appear yellow or red
should be replaced using the following instructions provided the vehicle
is equipped with an orange sticker displayed near the front of the engine
compartment which reads WARNING: HIGH VOLTAGE.
Take your vehicle to your Lincoln Mercury dealer for service if:
²One or both of your low beam headlamp bulbs are burned out and the
orange sticker which reads WARNING: HIGH VOLTAGE is not
displayed near the front of the engine compartment or
²The message center displays ªCHECK HEADLAMPS.º
