DESCRIPTION AND OPERATION
DESCRIPTION AND OPERATION OF GT
HEADLAMP MECHANISMThe concealed headlamps are moved mechanically.
Pushing actuating lever on left side of console opens
headlamps, pulling lever closes headlamps. Two
meshing gear segments convert the movement of the
lever to a rotation of 180 degrees. The pivots of the
headlamps lie below the centerline so that with head-
lamps in closed position the headlamp housing is
flush with front sheet metal.
A white indicator lamp in the instrument panel lights
if the headlamps are not completely opened and
locked. The switches of the headlamp electrical sys-
tem are located behind the left headlamp operating
mechanism.
MAINTENANCE AND ADJUSTMENTS
ADJUSTMENT OF HEADLAMP MECHANISMBoth headlamp assemblies must operate in unison in
order to lock in either the open or closed position.
