It would have been between September 1979 and April 1981 says Wikipedia.
We had red, yellow, and green LEDs by then. While I don't know the history, I stuck "green led" into archive.org and found things like "At one-fifth the current, these red, yellow and green LED seven-segment numeric displays are equal in brightness to the previous displays." in a 1975 advertisement at https://archive.org/details/sim_i-d_july-august-1975_22_4/page/n71/mode/2up?q=%22green+led%22 https://archive.org/details/sim_i-d_july-august-1975_22_4/pa... .
Though I think you mean high-intensity green?
That said, what green lights do you mean? The closest I could spot was in the skates, and they didn't look all that green. Can you give a time code?
The shots are only a few seconds long. There's plenty of time to replace batteries as needed.
Or perhaps it's more that they reflect green well, rather than emit green?
