There are different incandescent and electroluminescent lighting systems that supply direct and indirect lighting in the flight compartment. The flight compartment lighting system contains instrument/panel integral lights, miscellaneous incandescent lights, and electronic displays bright/dim control. The integral lights of different instruments and panels come on inside those units. The miscellaneous incandescent lights supply an external lighting on the instruments, controls, and panels, and lighting to the remaining flight compartment areas. The light intensity of electronic displays is controlled by three dedicated BRT/DIM rotary controls. Controls for the flight compartment lighting system are found on two COCKPIT LIGHTS control panels installed on the center pedestal. The flight compartment lighting system includes the systems that follow:

Panel Integral Lighting

The panel integral lighting supplies all of the legend/edge lighting for the instruments, instrument panels, and control panels in the flight compartment. The integral lighting contains incandescent lamps which are inside the instruments and electroluminescent lights which are inside the plastic panels. The intensity of the integral lighting is controlled by five rotary controls installed on the COCKPIT LIGHTS (INTEGRAL) control panel in the center pedestal. These controls are identified as: L (left), CTR (center panel, center pedestal, and glareshield), R (right), CB (circuit breaker panel), and OVHD (overhead panel).

A master switch controls the ON/OFF/AUTO functions of the integral lighting system through the EMS CDUs.

Standby Instrument Lighting

The standby instrument lighting is energized from the battery bus when usual DC power is off. The standby instrument lighting is controlled by the CTR BRT/DIM rotary control on the COCKPIT LIGHTS (INTEGRAL) control panel.

Miscellaneous Lighting

The incandescent floodlights are controlled by three rotary controls installed on the COCKPIT LIGHTS (FLOOD) control panel. They are divided into three groups/areas: (L) left panels/console, (CTR) center instrument panels, and (R) right panels/console. Each group has five or six lamps that supply general lighting for the instrument panels and side consoles. The pilot's and copilot's floor lights give lighting to the pilot's and copilot's feet, and the center aisle. The dome lights give lighting to the pilot's and copilot's seat areas. The two flight-crew reading lights have intensity and on/off controls integral to each unit. The eye reference, area, floor, and phone lights are controlled by toggle switches on the bottom of the COCKPIT LIGHTS (INTEGRAL) control panel in the center pedestal. The PBA BRT/DIM toggle switch controls the intensity of the annunciator lights. All the miscellaneous lights are an incandescent type except for the eye reference lights, which are light emitting diodes (LEDs).
