TM 1-1510-218-10 2-112 Section X.  LIGHTING 2-85.  EXTERIOR LIGHTING. a.   Description.    Exterior  lighting  consists  of  a navigation  light  on  the  aft  top  of  the  vertical  stabilizer,  one   navigation   light   on   each   wing   tip,   two   strobe beacons, one on top of the vertical stabilizer and one on  the  underside  of  the  fuselage  center  section,  one combination landing/taxi light recess mounted in each wing tip   C  ,  or  dual  landing  lights  and  one  taxi  light mounted  on  the  nose  gear  assembly    D    T  , and two ice   lights,   one   light   flush   mounted   in   each   nacelle, positioned to illuminate along the leading edge of each outboard wing.  In addition, some aircraft are equipped with a recognition light located in each wing tip.  Refer to Figure 2-30. b.  Navigation Lights.   The navigation lights are protected   by   a  5 -ampere  circuit  breaker,  placarded NAV,   on   the   overhead   circuit   breaker   panel.      The lights are controlled by a switch, placarded  NAV  ON, on the overhead control panel. c.   Strobe  Beacons.    The  strobe  beacons  are dual    intensity    units.        They    are    protected    by    a 15-ampere   circuit   breaker   placarded    BCN   on   the overhead circuit breaker panel.  Control of the lights is provided    by    a    switch    placarded    BEACON     DAY NIGHT.    Placing  the  switch  in  the   DAY  position  will activate  the  high  intensity  white  section  of  the  strobe lights   for   greater   visibility   during   daytime   operation.   Placing the switch in the  NIGHT position activates the lower intensity red section of the strobe lights. d.  Landing/Taxi   Lights.      Dual   landing   lights and a single taxi light are mounted on the nose gear assembly.      The   lights   are   controlled   by   switches placarded LANDING and  TAXI located in the LIGHTS section of the pilot's subpanel.   The control circuits are protected  by  two  5-ampere circuit breakers placarded LANDING  LIGHT  TAXI  LDG  on  the  overhead  circuit breaker panel.   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 cockpit floor. e.   Ice Lights.    The ice lights are protected by a 5-ampere    circuit    breaker,    placarded    ICE,    on    the overhead    circuit    breaker    panel.        The    lights    are controlled   by   a   switch,   placarded   ICE   ON,  on  the overhead control panel.  Prolonged use during ground operation  may  generate  enough  heat  to  damage  the lens. f.    Recognition    Lights.       A    RECOG   switch, located    in    the    pilot's    subpanel    LIGHTS    section, controls a white recognition light in each wing tip.   This steady   bright   light   is   used   for   identification.      The system  is  protected  by  a  7.5-ampere  RECOG  circuit breaker located on the overhead circuit breaker panel. 2-86.  INTERIOR LIGHTS. a.   Description. (1)   Interior    Lighting    C    D    T1    .        Lighting systems  are  installed  for  use  by  the  pilot  and  copilot and by the passengers in the cabin area.   The lighting systems   in   the   cockpit   are   provided   with   intensity controls   on   the   overhead   control   panel.      A  switch, placarded MASTER PANEL LIGHTS, on the overhead control   panel,   provides   overall   on-off  control  for  all engine  instrument  lights,  pilot  and  copilot  instrument lights, overhead panel lights, console and subpanel. (2)   Interior   Lighting   T2   .         Aviation   Night Vision  (ANVIS)  compatible  lighting  is  installed  in  the cockpit and cabin area.    The cockpit lighting systems are  provided  with  individually  controlled,  from   OFF to BRT  (bright)  rheostats  on  the  overhead  control  panel.   Cabin lighting is controlled by two switches, placarded CABIN  LIGHT  ON  /  BRIGHT   and  READING  LIGHT ON respectively. A switch,  placarded  MASTER  PANEL  LIGHTS, on   the   overhead   control   panel   provides   an   overall power   on-off  control  for  all  engine  instrument  lights, pilot and copilot instrument and gyro instrument lights, instrument     indirect     lights,     overhead     flood     lights, overhead panel lights and electroluminescent edgelights.
