Richard -
I used a lamp version of an NKK series lighted switch and they work very
well. They are LED's. We felt that they need to be dimmed a bit for night,
which can be done in our circuit with a couple of zener diodes.
Contact me off list if you are interested in the specs, wiring diagrams,
catalog (.pdf), sources and pictures of the annunciator panel.
Cheers,
John

Hi Richard-
Here's the approach I used. Has worked quite nicely for almost 300 hours so
far, day and nite. Click on >>Next Entry>> at top of page for sebsequent
pages. Maybe you can get some ideas here.

Richard -
I'm sorry I forgot to attribute a lot of credit to Mark. He shared his
system with me early on and I used the basics of the schematic in mine. It
is a rock solid piece of work. Since the lights are different, the actual
wiring and hardware reflect this. Check this for some pictures of the
panel & annunciator lights:

FYI to the list:
Through Vx Aviation, www.vx-aviation.com, I've developed several
annunciator lamp fields and controllers. Most of the circuit diagrams
are published for those who prefer to build them from scratch.
For those who don't, I sell pre-made arrays and controllers, as well as
an integrated controller/lamp array.
The real problem with annunciator lamps (besides how to label them) is
how to take all of the different sources (active high, active low,
reversing, etc.), drive the lamps and make them dimmable for night
operation. That's where the Vx controllers come in.
If any one has questions, they can contact me off list.
Thanks, Vern Little
