indicator lights

I saw the "kings of Sim" a good program. After watching that program, I have decided to build one myself. There is a bit of info on it (not much at the mo) at www.seething-airfield.co.uk under the simulator section.

I have a bit of a query. How do I get out of flight sim, information to turn on/off external indicator lights, vibrations (stall, landing ect)?

Thanks
