PASSENGER INFORMATION SIGNS
CARGO AND SERVICE COMPARTMENT LIGHTING
The cargo and service compartment lights are installed in various compartments and accessory areas to facilitate passenger and cargo loading, area inspection, and servicing. Control switches are installed in the compartments adjacent to the access door. When the forward, mid, or aft cargo door is closed, a portion of the door contacts and closes the light switch guard thereby turning out the cargo compartment light. The cargo compartment lights can also be operated by switches on the cargo compartment ceiling.
The nose gear wheel well, main gear wheel well, and forward accessory compartment lights are controlled by a switch on the external power receptacle panel.
The main gear wheel well lights are also controlled by a switch adjacent to the periscope viewing port in the passenger compartment floor.
Electrical / electronics compartment lights are controlled by a switch near the access door.
The fuel and water service panel light switches are installed on the respective fuel and water service panels.
Tail section area and aft accessory compartment service lights can be operated by either of two switches. One is located adjacent to the aft accessory compartment access door and the other is located on the passenger aft entrance stairway interior control panel.
Forward passenger door stair lights may be turned on to illuminate the forward stairwell door by holding a switch, located in the electrical / electronics compartment, in the down position. These lights aid in the inspection of the Forward Stairway door– an MEL maintenance function.

CARGO AND SERVICE COMPARTMENT LIGHTING - CONTROLS AND
INDICATORS
EXTERIOR LIGHTING
The exterior lights consist of wing and nacelle floodlights, forward and aft position and strobe lights, ground floodlights, anti-collision lights, logo lights, and landing and taxi lights.
The wing and nacelle floodlights are installed in each side of the fuselage to visually check the engine nacelle and wing leading edge for icing conditions. The lights also have sufficient disbursement to facilitate ground servicing and fueling and to aid in taxiing.
The wing tip position and strobe lights include forward position lights consisting of a red light on the left wingtip and a green light on the right wingtip. A white strobe light assembly is also installed in each wingtip adjacent to the forward position lights. A clear wingtip lens fairing covers each forward position / strobe light. A combination aft white position light and white strobe light assembly is installed in the trailing edge of each wingtip.
Note: Wing tip strobe lights operate only when POS/STROBE lights switch is at BOTH and nose wheel is off the ground.
The ground floodlights provide area lighting for ground service and aid side and forward visibility while taxiing.
Anti-collision lights are installed on the upper and lower fuselage surfaces.
The landing and taxi lights consist of the nose gear landing and taxi lights and the wing landing lights. Two sealed-beam, fixed-position, combination landing and taxi lights are installed on the nose gear assembly. The circuit is interlocked with the landing gear control relays so that the lights will come on only when the landing gear control handle is in the down position. One sealed-beam retractable landing light is installed on the lower surface of each wingtip. Each light assembly is enclosed in a housing and contains a motor to retract and extend the lights.
Note: With a single engine failure, wing landing lights will turn off and
retract automatically when landing gear is retracted after takeoff or
go-around.

EMERGENCY LIGHTING
Emergency lighting consists of lights for illumination of the cockpit and passenger compartments, the aft passenger stair and tail section; lighted overwing exits signs in the passenger compartment; aisle path lighting, and exterior overwing emergency evacuation lights. The lights are powered by rechargeable battery packs that supply power for approximately 15 minutes when fully charged.
Emergency lighting is controlled by an emergency light switch located on the overhead panel. When the system is armed, the emergency lights come on automatically if power is removed from the emergency DC bus.
