Unfortunately I don't think those are modeled within the fs2004 or fsx sims.  As far as I know, they are pretty aircraft specific as to what sets them off... and when you see such things on add-on aircraft, they are held in "systems logic" that is created within the panel structure of the airctraft itself.

Usually you can't access that kind of system from external sources unless the panel author provides FSUIPC offset or keypress access.  And 99.9999999% of add on panel authors don't do that.  (There is a REAL need of standardization for this kid of stuff in the flight sim community.)

I think the only way to implement this for your sim is to write the code that activates them yourself.  Or get something like Project Magenta (about $2000) that probaly handles that stuff and provides FSUIPC offsets for the outputs.  I am not sure but eventually the Ellie Avionics Systems software might be providing that kind of functionality at a MUCH lower price point .... but I don't know that for sure.

I have the exact same problem on my glare shield.  I have the indicator switches and labels..... and they are hooked up to Phidgets to activate them.... but no code yet to light them up.

best,
