They're available from a LOT of companies. Many of the sources have
standard socket configurations for multicolor LED arrays. I think if
you did a web search simply for "LED" you'd run across some of 'em
pretty quick. Finding "standard" (mechanically, anyway) sockets that
would support turning on just one color at a time might be a little
harder, but I don't doubt they exist. Geez, just look around. If you
still have trouble then reply again.

Also, as someone else pointed out in another newsgroup, multicolor
individual LEDs are available where when one uses DC with one polarity
the color is red, when the polarity is reversed the color is green, and
when AC is used the color is amber. One LED may not be enough to
illuminate things as you want, but several of them wired in parallel
should do the trick . . . maybe.

I had looked at earlier, and they do have LED lamps for suitable industrial
pilot lights - available in any _single_ colour you want. This seems to be
true of all other manufacturers I've located. There are multi-coloured
arrays (composed of single colour LEDs), but not suitable for industrial
use, or at least not without significant re-tooling of existing control
panels, which are already laid out for round industrial pilot lights.
Not sure about multicolored, they seem to have quite a variety.

Since readily available multiple-color Industrial LED lamps haven't
appeared, you might consider using a small display instead, like what

Thanks for the input, Sean.
I'm not certain of the type of display you are suggesting. The possibility
of moving to a small AB Panelview display has already been suggested, and is
under consideration. However the (large) difference in price mandated
investigation of other (cheaper) solutions. Altering existing display lamps
is quick, cheap and could provide sufficient additional indication. Of
course a decent LCD display has other significant benefits - which is the
reason this route has not been entirely cast aside.
I found "Bi-colour" and "Tri-colour" panel-mount LEDs here:
(I don't really get this, because these LEDs are typically implemented as a
red and a green LED on a single substrate - the third colour (amber) is
created by alternately strobing the red and green LEDs - so in theory, their
"bi-colour" LEDs _are_ "Tri-colour" LEDs (?)).
However, what I'm looking for is something more like the
215,216,217,218,225,231,or 234 series on this page:
These bulb-replacements would drop right into the existing lamp holders. If
I could find a "Tri-colour" filament replacement lamp and fit a colourless
translucent lens to the lamp holder, I'd be in business.
