LED Interior Lighting Sets

General Features
The ESU LED Interior lighting set 50703 uses the most
contemporary technique to supply its 16 yellow and
16 warm-white light-emitting diodes (LEDs) with a
constantly smooth and warm light. Thanks to its small
measurements it is universally usable for gauges 0 to G.
The following features make the ESU Interior lighting
sets so special:
•Pre-installedconstantvoltagesourceforaconstantly
bright and even light, independent of the track volta-
ge.
•Individually adjustable brightness: Yellow LEDs and
white LEDs be set separately.
•Thelightingboardscanbecutoffarbitrarlytotthe
cars of all manufacturers.
•Tobridgeprolongedpowerinterruptionsa„Power-
Pack“energystorageisalreadyinstalled.

Warning Notices - Please read before use
•TheLEDInteriorlightingsetsareexclusivelyintended
for the use with electrical model train layouts.
•Thesupplyvoltagemustbeswitchoffanytimewhile
connection work is carried out!
•Whenconnectingthelightingsetspleasealwaysstick
totheprinciplesexpressedhereinthismanual.
•Protect from humidity! Please do not unnecessarily
bend the lighting boards to avoid damage.
•ThecolourandthebrightnessoftheLEDsmayvaryalittle
within the framework of manufacturer‘s tolerances.
Installation
Firstofallthelightingboardshouldbeshortenedto
the required length. In order to do so break off the
lighting board by hand at one of the pre-carved and
marked cut-off points (as shown in gure 1). When
breaking off the board please make sure that none of
the components and conducting paths will be damaged;
thecircuitboardismeanttobreakattheexactdesired
point!Alternatively,youcanuseasaw.
Oddments can be connected to other interior lighting sets,
providedthatthemaximumof32LEDsisnotexceeded.

If not needed, remove the taillights.
Youmightneedtoshortenthesolderedsupplyingcables
totherequiredlength.Allleftandrightterminalpoints
on the lighting board are already connected with each
other.Thereforeonecablepersideissufcient.Oneside
will be connected with the left collector, the other side
withtherightcollectorofthewaggon.Polarityisnot
important,everylightingboardhasaninternrectier.
If your waggons have current-carrying couplers connect
the two supplying circuits alternatively with the coupler
contacts.
Fix the lighting boards under the carriage roof with
double-faced adhesive tape. Alternatively you may
sweep the interior equipment for appropriate anchorage
points. In many cases toilet facilities / rest rooms are
perfectly suitable for this purpose.
Brightness adjustment
Viathepotentiometersasshowningure2thebright-
ness of the yellow and white LEDs can be individually ad-
justed,asdesired.Withaskillfulbrightnessadjustment
youareabletomixyourdesiredcolorshade.

PowerPack
Theasstandardpre-installed»PowerPack«energysto-
rage ensures that the lighting functions are maintained,
also during a longer-lasting current interruption (e.g. in
frontofredsignals).Wireconnectionsarenotnecessary,
the functions works fully automatically.
Taillight
The taillight can be used on both ends of the lighting
board. Please consider the correct polaritay when
soldering the wires.

Digital operation
If you wish to switch the circuit board digitally you need
theLokPilotFxV3.0decoder,ESUOrderingno.52621.
TheLokPilotdecoderisamultiprotocoldecoderand
can be used for DCC, Motorola® or analogue AC
operation.
Youonlyneedtoremovethedummyconnectorfrom
thecircuitboardandplugonthedecoderinstead.Please
make sure that the polarity is correct and the decoder
is seated correctly!
Without having to change the settings after the in-
stallation the lighting board is now switchable with
F1. The taillight is switchable via the lighting key F0
(direction-dependent).
