transmitter relay.
In
this
event, the navigation light switch should be
turned
off
to
isolate
the
circuit;
then
reset
the
circuit breaker
to
re-acti-
vate the
transmitter relay
and
permit its
usage.
Do
not

LIGHTING EQUIPMENT.
EXTERIOR
LIGHTING.
Conventional navigation
lights
are
located in the wing
tips
and
tail
stinger.
Two
landing
lights are installed
in the
cowl
nose cap.
When
taxi
lighting
is selected,
the
left
cowl light
illuminates separately.
De-
pressing
the adjacent landing light switch
causes
both
lights
to
illuminate
and
serve as
landing
lights.
Optional lighting includes a
flashing
beacon
which mounts
on
the top
of
the
vertical
fin,
two
strobe lights
(one
in each
wing tip),
and two
courtesy
lights
(one
under each wing
just
outboard
of
the cabin door). All
exterior lights
except the courtesy
lights are
con-
trolled
by
rocker-type
switches located
on
the
left
switch
and
control panel.
The courtesy
lights are operated
by a switch
on
the aft side
of
the
left
rear
door
post.
The
flashing beacon should not
be
used when flying through clouds or
overcast;
the flashing light
reflected from water droplets
or
particles
in
the
atmosphere, particularly at
night, can produce
vertigo
and
loss
of
orientation.
The
two
high
intensity strobe lights
will enhance
anti-collision pro-
tection.
However, the lights should be
turned
off when
taxiing in the
vicinity
of
other
aircraft,
or
during flight through clouds,
fog
or
haze.
INTERIOR LIGHTING.
Instrument

electrolumines-
cent lighting, flood lighting, optional

concentric
rheostat
control knobs labeled
"LWR PANEL,
ENG-RADIO,
v
and
a rheostat
control knob labeled

intensity
of

and
control panel lighting.
A
rocker-type
switch labeled
1"
POST-FLOOD
LIGHTS"
is
used to
select either standard
flood lighting or
optional
post
lighting.
These
controls are
located on the
left
switch
and
control
panel.

and
controls
on
the lower
part
of
