204 Cab Interior and Sleeper
Sleeper Section
The sleeper section has individual bunk
light fixtures for all types of sleeper cabs.
They are of the same type as the front
overhead lights. They are operated by the
switch on the fixture.
There are overhead fluorescent lights in the
VN-610, VN-660, and VN–770.
The fluorescent overhead lights can be op-
erated from the sleeper panel switch.
For the VN-770 model, there is also a
switch for the overhead fluorescent light in
the left hand switch cluster on the dash.
This switch can be reached from outside
the cab door to enable the light to be turned
on without having to climb into the cab.
