 |
|
Although it doesn't have nearly the features of Alan's proposed annunciator,
I built a custom annunciator panel for my Bonanza. It has 16 LED outputs, 13
Stanley bar LEDs and 3 discrete LEDs for marker beacon lights (amber, blue,
white). Except for the marker beacon LEDs, each output can be driven by a
low or high signal. It has a test button, of course. The circuitry is pretty
basic, mostly some surface mount transistors, diodes and resistors. It dims
at night by being connected to the dimmer circuit (switched by the nav light
switch).
I designed and machined an aluminum housing for it, so that it mounts with
six screws from behind the panel above my six pack. You can see a photo at:

The annunciator photo is near the bottom. I'd be glad to provide more info
if anyone is interested...
