Pretty sure this is a bug, so I wanted to report it here...when I switch the External Lights Master Switch to OFF, as it is currently modeled, it physically changes/moves all external light switches/knobs positions to OFF in the cockpit. I don't believe that is how the Ext Lights Master Switch should function, I believe that all other switches/knobs should remain set to ON (or however they were set previously), but simply that the power to the external lights should be cut. This allows the lights to be set to preference during start-up and then turned ON/OFF in flight with the ease of one Master switch.
