Subject: AeroElectric-List: Comparison of LED annunciator fixtures

A few days there was some discussion about some
off-the-shelf, led annunciator fixtures offered
on eBay:

I ordered in some of these and found that they
were reasonably bright, mechanically rugged
with the only down-side being the lack of
vibration support on the smash-em terminals
at the back.

I ordered some samples which arrived yesterday.

They're certainly good looking and mechanically rugged.
They're biased up with a resistor spliced into the
pigtails under heat shrink. As received, they're
set up to consume less than 10mA at 12-14v.

I'm pretty sure these lamps will easily handle 30
mA of excitation which gets you a bit more intensity.
These may well be suited to your annunciation task.
Consider replacing the existing series resistor
with a 330 Ohm, 1/2 watt resistor.
