Have you considered LEDs? There are TONS of sources out there for them. Large, Small, Medium... You name it. Just search 12v led indicator on google. I spent days searching thru the results from google before I decided on which one to do. Plenty of good choices. The other thing to consider is that the markers aren't required if you have a different way to identify the fix.
There are a very few rare approaches where there is nothing but an OM marker beacon to mark the FAF for a localizer-only approach. In those cases, you can't get by with DME or an ADF, but the FAF should be identifiable with a GPS that has the fix in its database. Note that some GPS's like the KLN-89B do not have non-GPS approaches in their database (and thus, no unnamed approach fixes) in their database, but more modern ones like the Garmin GNS430 do. In addition, as noted above, marker beacon receivers are required equipment for Cat II/III ILS approaches, but not too many of us do those.
There is always the flashing light factor. The more stuff the cooler it looks.

Does anyone have a resource for 14V White, Amber, and Blue indicators.
I am reorganizing my panel and the audio panel (PS Engineering PMA7000M-S) is going to be out of easy field of view for approaches. The PMA7000M-S has pins on the connector for remote lights so it won't be too hard to wire it up. The real problem is that I'm finding it really hard to find small incandescent lamps.
I'd love to find some Dialight 507-3914 series 14V cartridge lamps and holders. They're just about the right size. I see them available in white and amber but no blue. There's a hole in the part number series where the blue one was and I've found a reference for them but it says "Obsolete" and stock "0". 
These are either Dialight 507-3914-1474-600 or MS-18235-2BT. Someone probably has a drawer full of them somewhere...

Bill;
A quick "Google" search reveals several suppliers with part number
507-3914-1474-600 in stock. (some are the "F" version which appears to be
the RoHS compliant model) Also some have minimums which will be a problem -
but-
http://www.masterelectronics.com shows 2 of the "F" model available to ship
http://www.onlinecomponents.com has 2 of the "F" model in stock for $4.95
ea
http://www.sierraic.com has 688 in stock
http://www.componentsmax.com says they have 51,800 in stock
http://www.harrykrantz.com shows 17 available
Why not an LED indicator which would have a better service life than the
incandescent model quoted??

Good Afternoon Bob and Bill,
May I ask why you want the marker beacon indication? It is/was part of the low frequency range system which was shut down over sixty years ago. It has been retained for use with a few ILSs and some NDB approaches, but such use is rapidly being discontinued.
I know of no fix designated by a marker beacon that cannot be found via some other legal IFR data.
That is especially true if one has an IFR approved GPS installed.
There is nothing wrong with having a marker beacon receiver installed, but you can eliminate an antenna and some wiring by getting rid of it. You might even be able to save some panel space.
My vote is to forget about the marker Beacon Receiver. <G>
Happy Skies,
Old Bob

Good Afternoon JM,
You mention that you need to have the fix in the GPS database to use it in lieu of the marker beacon. That is not completely correct. If there is any other fix along the same course that IS in the database, A distance from that fix may be used. Check out the section in the AIM that has to do with using the GPS in lieu of ADF and DME. That and other uses are covered quite well.
Happy Skies,
Old Bob

Maybe I'm missing something, but the color filters on the face of the PS Engineering PMA7000M-S were made to light up with plain old sort-of-white lamps.
Wouldn't white LEDs do fine?

Thanks...
Yeah, I'm considering all sorts of things. I like those Dialight lamps
because they don't glare like LED's tend to do. I guess I could take
some sandpaper to some LED's and fix that problem.
I'll take a look at the sources you listed.
Thanks again, Bill
