Testing some new overhead circuitry

So the overhead panels are back up once again, although with the circuitry for the fire handle units now fully operational. Below is a short video of us testing them. The 'slave' landing gear indicators are also demonstrated here. 

In an actual aircraft, in which redundancy is essential, these would be driven completely separate from the those located on the main instrument panel, although here (for the sake of efficiency) their data is derviced from the same place.
