Possible to have External Physical Indicator light for On/Off-Duty status?

I work on a team where we have to manually set ourselves as Available in order to be in the call queue. I'm terrible at remembering to flip my status both when leaving and coming back. I don't suppose anyone knows if there is a way to have an external LED light of some sorts (maybe fed thru a StreamDeck type device?) that shines red or green to reflect my current On or Off Duty status?
