Interior Lighting
Interior lighting for the airplane consists of separately controlled
incandescent overhead lights for general cabin lighting, individual
lights for the pilots and passengers, and dimmable panel floodlights.
The flight instrumentation and avionics equipment lights are dimmable.
Instrument Lights
Instrument lighting for the airplane consists of photocell backlighting
technology for the flight displays, bezel, audio panel keys, FMS
keyboard, and optionally installed GMC 705 AFCS Control Unit and
dimmable incandescent lights in the standby instrument bezels.
Components using backlighting technology automatically adjust for
ambient lighting conditions. Manual brightness adjustment for all
instruments can be accomplished through the INSTRUMENT dimmer
control on the instrument panel bolster. The instrument light circuits
operate on 28 VDC supplied through the 5-amp CABIN LIGHTS circuit
breaker on MAIN BUS 1.

A string of red LEDs mounted under the instrument panel glareshield
provide flood lighting for the instrument panel. The lights are controlled
through the PANEL dimmer control on the instrument panel bolster.
The panel lights operate on 28 VDC supplied through the 5-amp
CABIN LIGHTS circuit breaker on MAIN BUS 1.
Reading Lights
Individual eyeball-type reading lights are installed in the headliner
above each passenger position. Each light is aimed by positioning the
lens in the socket and is controlled by a push-button switch located
next to the light. The pilot and copilot reading lights are also dimmable
through the PANEL lights control on the instrument panel bolster. The
reading lights are powered by 28 VDC supplied through the 5-amp
CABIN LIGHTS circuit breaker on MAIN BUS 1.
Overhead Dome Light
General cabin lighting is provided by a dome light located in the
headliner at the approximate center of the cabin. The dome light is
controlled by the switch next to the light assembly on the ceiling of the
aircraft. The dome light is powered by 28 VDC supplied through the 5-
amp CABIN LIGHTS circuit breaker on MAIN BUS 1.
