A. General Instrument Panel Lighting
Two lights give general lighting to the instrument panel. They are located below the roll bar.
Each light gives a flat beam. You can adjust the angle and direction of the beam. The switch for
the instrument panel lighting is located on the instrument panel. The instrument panel rheostat
controls the brightness of the lights.
Some aircraft may be equipped with a backlit instruments, controlled by a combined switch/pot
located on the instrument panel

C. Instrument Panel Rheostat
The instrument panel rheostat is located beside the instrument panel light switch. It controls the
brightness of the general instrument panel lights. In aircraft equipped with backlit instruments
the brightness is controlled with a combined switch/pot located on the instrument panel
D. DIM/BRIGHT Switch
The DIM/BRIGHT switch is located beside the rheostat. It controls the internal light for the
magnetic compass. It also controls the brightness of the flap and trim controls. (The switch can
also control the brightness of some avionic equipment displays. See the related Chapter or the
