Ordered in a batch. The price is certainly
right. Unlike many turn-key indicators of
yesteryear, these are nice and bright. Further,
they have two leds back to back so they
light up with either polarity of DC voltage
. . . which means they work on 12 volts
AC as well.
The only 'downside' are those mash-a-wire
screw connectors . . . used 'barefoot', this
style connection offers no vibration support
for the lead wire. Yet another use for a
dab of E6000?
They 'come alive' at 3 volts applied with
a draw of only 1 milliamp. Would be useful
as an indicator driven by the logic output
of a microprocessor. At 14v they
draw about 11 milliamps.
Just for grins, I put one on the bench supply
at 29v. It draws 25 milliamps and is expectedly,
quite bright. I'll let it 'cock' for awhile.
I expect the fixture to get noticeably
warm in free air . . . it would, no doubt
run cooler if mounted to a panel.
Poked around for a few minutes to see if anyone
offered this product in other colors. No joy.
I did find a bunch of LED products in metal
housings.
Will let you know if they 'cook off' in a
28v system. I'm betting they'll be just fine
for warning light service (intermittent duty)
Watch this space . . .
My office and shops are migrating to all LED
as new lights are installed and old fluorescent
fixtures are replaced.
Check out the array of surface mount, flat
panel led products too. I've used 12" square
and 24" square fixtures in the house. My contractor
had me build hardwood frames to install 5
fixtures in a local office remodel. Reasonably
priced, lots of light. Even tho the flat panel
lights are arrays of hundreds of LED junctions,
you cannot see individual lamps through the
translucent overlay. Very pleasing effect.

Bob,
Dimensions of LED indicators?
Mounting hole dia:
Bezel dia:
Height overall:
and speaking of fluorescent to LED conversion..
I converted one of my shop lights, an 8-ft, 4-bulb fixture, to LED around Christmas time. The LED bulbs are a little bit brighter than fluorescents, produce full brilliance instantly in cold weather, no 60-cycle hum, and no RF interference on my FM radio in the shop. They draw 1/3 the current and, in theory, should outlive me. The fixture must be re-wired to take the ballast out of the circuit, but that is easy.
I bought 4 bulbs on Amazon for about $120 (back in December). Very please w/ result.

Those are nice switches indeed. There's a whole universe of similar products on eBay and AliExpress. One of the leading manufacturers is a company called ONPOW. They offer many styles, diameters, switch actions, illumination colors (including RGB) and even mounting panels and boxes. See: http://onpow.com/en/
eBay's selection is limited, but AliExpress has many of their products for sale. Search: "onpow".

This set might be interesting - can't tell how bright they are, but the
price is pretty good!
http://tinyurl.com/lku77uc
And these look pretty similar to the one you tested, but come in
multi-colors. Again, the price is right!

These appear to be 5mm lamps . . . similar to
fixtures we used to supply with the AEC9005
except we didn't scab resistors into the lead
wires.
[img]cid:7.1.0.9.0.20170508132348.0545cdf0(at)aeroelectric.com.0[/img]
Those indicators appear to have leads tacked
onto the stock LED lamp leads . . . no bending/
vibration support.

Those look promising . . .
I've ordered in one of each color. Will
report on findings when they get here.
