 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...

Hi Nathan:
	




I saved your e-mail for a time when I wasn't so busy, thus the delay in 

responding. 



I would like a little more info on your annunciator.  As I am somewhat 

electronically challenged, your circuitry would be of particular 

interest.  Beautiful machining, by the way.



Thanks,



Al Etherington

Greetings Nathan,



	I would like to get a copy of the schematic for your panel. I don't think

I'm up to working with SMT components but I might try it with larger

components.



Thanks.
