Operation
The OFF-BRIGHT control for P1, P2, and P7 instrument and
panel lights adjusts the intensity of the lamps.
Functional Description
The OFF-BRIGHT control is a variable transformer. The control
knob turns to adjust the voltage available to the fixed
transformers in the captain’s lighting module (P41).
The lighting module’s fixed transformer supplies a maximum of
5v ac to the circuit breakers on the P41 panel. The 0-5v ac
voltage from the circuit breakers makes the P1, P2, and P7
instrument and panel lights come on.
Instruments that are necessary for flight safety connect to the
standby light system. When power is not available from transfer
bus 1, the lights get power from the standby bus. When relay R1
does not energize, the standby bus connects to the standby
transformer, T2 in P42. The standby transformer supplies the 5v
ac to the lights that are connected to the system.

Purpose
The lightplates supply light to these components:
* Panel decals
* Instrument lights
* Panel switches.
Physical Description
The lamps are a part of the lightplates. The back of the
lightplates have an electrical connector on a printed circuit
board. The incandescent lamps are in a parallel circuit. The
lightplate continues to supply light if one lamp has a failure.
The front of the lightplates have etched letters and openings for
selector switches and indicator lights. These openings let the
lamps on the circuit board to supply light to the front of the
panels.
Location
There are integral panel lights in the lightplates on these
panels:
* P1 captain instrument panel
* P2 center instrument panel
* P3 first officer instrument panel

Purpose
The indicator lights show the flight or maintenance crew the
condition of an airplane system.
Location
Many airplane systems have indicator lights in the flight
compartment. Indicator lights are on these panels:
* Instrument panels
* Overhead panels
* Electronics (aisle stand) panels.
Physical Description
The indicator lights use incandescent lamps to supply light.
Each indicator light has these components:
* Terminal assembly
* Sleeve
* Body and contact assembly
* lamps
* Cap assembly
* Mounting screws.
Functional Description
The two types of indicator light assemblies receive either a
ground or power. The indicator lamps that have a ground come
on when an electrical ground is on the output terminal. The
indicator lamps that receive power, come on when a positive
16/28v dc is applied to the output terminal.
Each type of indicator light assembly has a press-to-test switch
circuit. This does a test of the lamp.
The lens of each indicator light assembly is colored. The lens
