master caution light.

I do not use PMSystem.
The Master caution bell sounds anyway on some occasions.

Is there a way to output a led to light up the MC annunciator when this happens?

In my case (767LD) the SDK offers a variable to know when the yellow or the right lights of the MC are on.

I think this post is good also for another question I have.
I am thinking how to build a MC for my 767 cockpit. I have written a little project (http://weyes-homecockpit.blogspot.com/2008/12/master-caution-button-project.html) and I have almost built it but I am not completely satified.

Can you suggest me a better implementation or a suitable COTS? All the switches I have found in my preferred electronic shop are too little and do not allow to fit two lights (red/yellow) inside.

I am not trying to replicate all the complexity of the real one.
Would just like to have a red led light up with the bell. (from a software source to interface)
I will manage the rest with a Korry.
Probably impossible but...?

I would think that if you know the offset that triggers the bell, you could use it to light up an LED using Phidgets for instance.
