   Thanks for the replies. I see they even have a two-color LED option, which seems nice to keep the label visible even when it’s off. Hope you start offering them.

     That’s right, I recall they offer a red/green single LED option based on reversed polarity..

     One thing to consider when using this two-color LED -it’s not ultra bright like the other single color LEDs.

     I want to apply a ‘dark cockpit’ philosophy so the LED is only lit when the system is not in the standard/normal operating mode.
