Thanks Kev...that makes so much more sense now....I can understand now. I
just couldn't understand why it wouldn't just be a button like so much
else..

But I can see now how important it would be if you say lost all power to the
cockpit instrumentation to be able to easily find the landing gear in the
dark if neccessary...

It all makes perfects sense...
