Emergency (fail safe) lighting

The light control module provides
emergency lighting in the event of an

hardware allows the following lighting
circuits to function:
Low beam headlights
Taillights
Brake lights
The headlights and taillights come on
as soon as the ignition is switched ON.
The brake light operates when the
brake pedal is pressed.
WARNING!

remove the fuse protecting the
circuit under repair. See
Electrical Component

should not be handled. Dirt and
skin oils may cause a bulb to fail
prematurely. If necessary wipe
bulb using a clean cloth
dampened with rubbing alcohol.
