light installations at the aft lavatory service panel, oxygen service panel,
water service panel and on the forward external electrical access panel.
The refueling panel light (and other service panel lights if installed)
operates from the 28V DC Essential DC bus in order that it may be
powered by the airplane batteries only. A proximity switch installed in the
panel door opens when the door is unlatched, completing the circuit to
power the light. Integrated into the circuit is a SERVICE DOORS
annunciation on the cockpit EICAS display whenever the panel is open.

2A-33-60: Emergency Lighting System
1. General Description:
The external emergency lighting system facilitates safe evacuation of the airplane
during an emergency in darkness or low visibility. The system is composed of the
following elements:
• Overwing Exit Lights
• Underwing Exit Lights
• Main Entrance Door Emergency Lighting
• Emergency Lighting Battery Packs
• Emergency Lighting Control Switches
2. Description of Subsystems, Units and Components:
A. Overwing Exit Lights:
There are three exit lights on each side of the airplane, installed in the
fuselage below the emergency exit windows. A light is located at the
forward, mid and aft wing root area to illuminate the top of the wing surface
as an aid in airplane evacuation.
B. Underwing Exit Lights:
An exit light positioned forward of the leading edge of the wing on each
side of the airplane illuminates the area beneath the wing. The light
facilitates judging the distance from the wing surface to the area below for
airplane occupants evacuating using the emergency exit windows.
C. Main Entrance Door Emergency Lighting:
Automatic activation of the main entrance door emergency lighting is
