inspection of equipment installed in the tail compartment.
(1) Tail Compartment Utility Lights:
Two incandescent dome lights are mounted on the tail compartment
overhead, one forward and one aft. The lights are controlled by
either of two switches. One switch, located in the tail compartment
on the left side near the entrance at the top of the ladder, switches
the lights on only when the tail compartment access door is open.
This arrangement prevents leaving the lights on unnecessarily. A
second switch, located on the panel on the forward bulkhead of the
baggage compartment (shown in Figure 6), controls the dome lights
regardless of access door position. This allows the ßight crew to
view the interior of the tail compartment during ßight through the
inspection window in the center of the pressure dome bulkhead.
NOTE:
With the tail compartment access door open and the
light switch in the tail compartment selected on, the
lights will illuminate regardless of the position of the
switch in the baggage compartment.
In addition to the incandescent dome lights, airplanes 1495 and
subsequent have wiring provisions for three ßorescent light Þxtures
that can be installed as an option during the completion process.
The optional Þxtures are typically installed on the compartment
overhead in locations requiring additional illumination. Control of the
ßuorescent Þxtures is with the same pair of switches used for the
incandescent dome lights, with the exception that power to the
ßuorescent lights is routed through the access door relay, limiting
the ßuorescent lights to ground operation only with the access door
open. (The incandescent lights remain available for compartment
inspection during ßight.)
Both the incandescent and optional ßuorescent light Þxtures are
powered by 28V DC from the Essential DC bus.

2A-33-50: Exterior Lighting System
1. General Description:
Lights installed on the GIV airplane exterior provide illumination for landing and
taxiing, airplane recognition and collision avoidance, and inspection of airplane
wing surfaces for ice formation during ßight. Service compartment lighting is
integrated into panels / access doors to facilitate refueling and resupply. The
following lights are installed as standard equipment on the GIV:
• Anti-Collision Lights
• Strobe Lights
• Navigation Lights
• Ice Inspection Lights
• Landing Lights
• Pulse Lights
• Taxi Lights
• Wingtip Floodlights
• Wheel Well Lights
• Ramp Lights
• Logo Lights
• Refueling Panel Lights
The location of exterior lights is shown in Figure 7.
2. Description of Subsystems, Units and Components:
A. Anti-Collision Lights:
Two red anticollision lights are installed on the airplane. The top
anticollision light is a red strobe light consisting of a Xenon ßashtube with
integrated power supply and a reßector, mounted on the upper center line
at Fuselage Station 308. The bottom anticollision light is either an
oscillating light assembly consisting of a motor, two bulbs, noise Þlter and
red lens (airplanes not having ASC 10) , or a red strobe light similar to the
top anticollision light (airplanes having ASC 10) mounted on the lower
center line at Fuselage Station 465.
Both top and bottom lights are controlled by the BCN switchlight on the
bottom section of the pilot overhead panel shown in Figure 8. When the
BCN switchlight is selected ON, 28V DC power from the Right Main DC
bus opens the ROTATING LTS BEACON (airplanes not having ASC 10) or
BEACON (airplanes having ASC 10) relay. The open relay routes 115V AC
