MODEL 172R (180 HP)
The exterior courtesy lights (and the rear cabin dome light) are
turned on by pressing the rear cabin light switch. Pressing the rear
cabin light switch again will extinguish the three lights. The
remaining exterior lights are operated by breaker/switches located
on the lower left instrument panel. To activate these lights, place
switch in the UP position. To deactivate light, place in the DOWN
position.
NOTE
The strobes and 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.
INTERIOR LIGHTING
Interior lighting is controlled by a combination of flood lighting,
glareshield lighting, pedestal lighting, panel lighting, radio lighting
and pilot control wheel lighting.
Flood lighting is accomplished using two lights in the front and a
single dome light in the rear. All flood lights are contained in the
overhead console, and are turned on and off with push type
switches located near each light. The two front lights are individually
rotatable, providing directional lighting for the pilot and front
passenger. The rear dome light is a fixed position light and provides
for general illumination in the rear cabin area.
Glareshield lighting is accomplished using a fluorescent light
recessed into the glareshield. This light is controlled by rotating the
GLARESHIELD LT dimmer, located below the nav indicators.
Rotating the dimmer clockwise increases light intensity, and rotating
the dimmer counterclockwise decrease light intensity.
