TM 1-1510-224-10 Section X.  LIGHTING 2-75. EXTERIOR LIGHTING. Exterior  lighting  (fig.    2-37)  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 flush 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. a. Navigation   Lights.      The   navigation   lights   are protected   by   the   5-ampere   circuit   breaker   placarded NAV  on  the  overhead  circuit  breaker  panel  (fig.    2-9). Control  of  the  lights  is  provided  by  the  switch  placarded NAV - ON, located on the overhead control panel (fig.  2- 15). b. 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.  2-9).  Control of the lights is provided by   a   switch   located   on   the   overhead   control   panel placarded BEACON - DAY - NIGHT (fig.  2-15).  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. c. Recognition   Lights.    The  recognition  lights  are operated  by  the  two-position  switch  placarded   RECOG, located in the pilot's subpanel.  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.  2-9). d. 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. The   landing   light   circuit   is   protected   by   the   5-ampere circuit   breaker   placarded    LANDING,    located    on    the overhead  circuit  breaker  panel  (fig.    2-9).    The  taxi  light circuit    is    protected    by    a    5-ampere    circuit    breaker placarded TAXI, located on the overhead circuit breaker panel  (fig.    2-9).    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 aisleway forward of the main spar. e. Ice Lights.  The ice lights circuit is protected by a 5-ampere circuit breaker placarded  ICE on the overhead circuit  breaker  panel  (fig.    2-9).    Control  of  the  lights  is provided    by    a    switch    placarded    ICE   -   ON    on    the overhead control panel (fig.  2-15). 2-76. 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.    A  switch  placarded   MASTER  -  ON,  located  on the   overhead   control   panel   in   the    COCKPIT   LIGHTS section  (fig.  2-15),  provides  overall  control  for  all  engine instrument  lights,  pilot's  and  copilot's  instrument  lights, overhead  panel  lights,  and  subpanel  lights.    The  switch placarded   IR   FLOOD   ON,   located   on   the   overhead control   panel   (fig.   2-15),   provides   overall   control   for instrument panel, glareshield, and pedestal extension/cockpit lights. a. Cockpit Lighting. (1) Utility lights.    Two  utility  lights  are  located on the cockpit overhead to provide additional instrument panel  lighting,  as  required.    The  lights  are  protected  by the 7.5-ampere FLT INST circuit breaker, located on the overhead  circuit  breaker  panel  (fig.    2-9).    Variable  light intensity,     for     both     lights     is     provided     through     the INSTRUMENT    PANEL    rheostat,    located    in    the    IR FLOOD LIGHTS switch section, on the overhead control panel.  Individual intensity control is provided by a switch placarded BRT - DIM OFF, located on each utility light. (2) Glareshield lights.    Lights  are  mounted  in the   glareshield   overhang   along   the   top   edge   of   the instrument  panel,  providing  overall  instrument  panel  IR illumination.      The   circuit   is   protected   by   a   5-ampere circuit    breaker    placarded     INST    INDIRECT     on     the overhead   circuit   breaker   panel   (fig.      2-9).      Control   is provided by the rheostat switch placarded GLARESHIELD  on  the  overhead  control  panel,  located in the   IR  FLOOD  LIGHTS   switch   section   (fig.      2-15). Turning the control clockwise from  OFF,  illuminates  the lights and increases their brilliance. (3) Flood   light.      A   single   overhead   cockpit flood   light   is   installed.      This   light   provides   overall   IR illumination   of   the   entire   cockpit   area.      The   circuit   is protected by a 7.5-ampere circuit breaker placarded  FLT INST, located on the overhead circuit breaker panel (fig. 2-9).        Control    is    provided    by    the    rheostat/switch, placarded    PED    EXT/COCKPIT,    located    in    the     IR FLOOD LIGHTS  switch  section  of  the  overhead  control panel  (fig.    2-15).    Turning  the  control  clockwise  from OFF, illuminates the light and increases its brilliance. 2-84
