2-79. EXTERIOR LIGHTING.
a. Description. Exterior lighting (Fig. 2-39) consists of: a navigation light on the aft end of the aft portion of the
vertical stabilizer; one standard navigation light on the outside of each wing tip pod; two strobe beacons, one on top
of the horizontal stabilizer (directly above the vertical stabilizer) and one on the underside of the fuselage section;
dual landing lights and a taxi light mounted on the nose gear assembly; a recognition light located in the outboard
leading edge of each wing; two ice lights, one light lush mounted in each nacelle positioned to illuminate along the
leading edge of each outboard wing; and emergency exit lights aft of the escape hatch and aft of the cabin door.
b. Navigation Lights. The navigation lights are protected by the 5-ampere circuit breaker placarded NAV on
the overhead circuit breaker panel (Fig. 2-12). Control of the lights is provided by the switch placarded NAV ON,
c. Strobe Beacons. The strobe beacons are dual intensity units. They are protected by the 15-ampere circuit
breaker placarded BCN on the overhead circuit breaker panel (Fig. 2-12). Control of the lights is provided by the
switch located on the overhead control panel placarded BEACON - DAY - NIGHT (Fig. 2-13). Placing the switch in
the DAY position will activate the high intensity white section of the strobe lights for greater visibility during daylight
operation. Placing the switch in the NIGHT position activates the lower intensity red portion of the strobe lights.
d. Recognition Lights. The recognition lights are operated by the two-position switch placarded RECOG , lo-
cated on the pilot s subpanel (Fig. 2-11). The lights provide a very bright, steady illumination. They are protected
by a 7.5-ampere circuit breaker, located on the overhead circuit breaker panel (Fig. 2-12).
e. Landing/Taxi Lights. Dual landing lights and a single taxi light are mounted on the nose gear assembly.
The lights are controlled by the switches placarded LANDING and TAXI , located on the pilot s subpanel 2-11. The
landing light circuit is protected by the 5-ampere circuit breaker placarded LANDING , located on the overhead circuit
breaker panel (Fig. 2-12). The taxi light circuit is protected by a 5-ampere circuit breaker placarded TAXI, located
on the overhead circuit breaker panel (Fig. 2-12). Landing/Taxi lights are automatically turned off when the landing
gear is retracted. The landing lights and taxi light power circuits are protected by 35-ampere and 15-ampere circuit
breakers, respectively, located on the DC power distribution panel, beneath the aisle way forward of the wing main
f. Ice Lights. The ice lights circuit is protected by the 5-ampere circuit breaker placarded ICE on the overhead
circuit breaker panel (Fig. 2-12). The switch provides control of the lights placarded ICE - ON on the overhead
2-80. INTERIOR LIGHTING.
Lighting systems are installed for use by the pilot and copilot. The lighting systems in the cockpit are provided with
intensity controls on the overhead control panel. The switch placarded MASTER ON , located on the overhead
control panel in the COCKPIT LIGHTS section (Fig. 2-13), provides control for engine instrument lights, pilot and
copilot chronometer, headset AHRS panel, PFD control panel, NAV control panel, weather radar control panel, RCU
panel, Rev disable switch, altitude select panel, overhead panel lights, and subpanel lights. The switch placarded
IR FLOOD - ON , located on the overhead control panel adjacent to the MASTER - ON switch (Fig. 2-13), provides
overall control for instrument panel, glareshield, and pedestal extension/cockpit lights. The annunciator DAY and
NIGHT switch is protected by a 5 amp circuit breaker located in the overhead circuit breaker panel (Fig 2-12), the an-
nunciator DAY and NIGHT switch is located on the copilot left knee subpanel (Fig 2-11), and controls intensity of pilot
and copilot annunciators. With DAY NIGHT switch in NIGHT position pilot and copilot annunciator intensity is con-
trolled by annunciator rheostats located above pilots and copilots chronometers. The miscellaneous Selector/Status
panel, mode Selector/Annunciator, and Autopilot Weather panel intensity is controlled by annunciator rheostat (Fig
2-19) located below # 2 MCDU. With the DAY and Night switch in DAY position all controllable annunciators default
to full bright.
