Dean,
The MD200-306 has internal lighting. But one gottcha.... Be sure that you
don't
put a dimmer circuit on it as it also has it's own internal dimmer...

I have a VOR/ILS indicator made by Mid Content Instruments (MD200-306)
and I
am trying to figure out if it is lighted internally or if I need to
supply
some sort of lighting. The (Spartan) instruction manual shows
lighting
connections but I'm not sure if they are for the annunciator lights or
for
full facial lighting. Those who've used this instrument in your
panels, do
you remember if it is internally lit or will I need to supply post
lights or
something similar? I emailed Mid Content Instruments several days ago
about
this but apparently their entire technical support department is on an
extended vacation! Thanks for all the help.

Pat,
I just looked up my wiring and found the following: Pin #21,22 to GND,
Pin #23 to dimmer, and Pin #19 to +14VDC.
I had originally wired Pin #23 (ann. PWR) to the dimmer, but found
that the unit had an internal dimmer associated with the enunciator.

Fred,
My pinout diagram for the MD200-306 shows that pin #23 goes to the 14
volt
dimmer, pin # 22 goes to either a 28 volt dimmer or to ground in the
case of
a 14 volt dimmer. Pin # 19 is for 14 v input and pin # 21 is the
power
ground. I wired mine this way and it dims very nicely with the dimmer
circuit. I was not aware that it had an internal dimmer as well. Can
you
clarify?
Documentation is sparse but I do have the pinout if anyone needs a
copy.
