esp if they both had indicator lights.


A simple visual cue might be to install the switches in a three way
arrangement such that the lights are off when the switches are pointed in
the same direction at both stations. Or vice versa if you prefer, but you'd
have to remember which it is and remember to look.

Any way you do it has advantages and drawbacks, IE with series switches
you're less likely to accidentally leave a light on, while with parallel
switches you're less likely to think you've turned a light on when you
haven't. Indicator lamps would mitigate most of that, but they'd add a
little current draw and some complication.




Sounds like a job for - Relays!
