I think they send 2 greens because just one green is not Dark enough. I bought some of these maybe 5-10 years ago and they gave you only 1 green. Recently I bought a set of these and they now give you 2 green, like you mentioned. I installed just one green in my dash and now when its on its not dark enough, you can see a lot of detail behind the green lense. You can clearly see the bulb itself and the metal gage holder that it sits in. When I pull the dash apart this winter to put the tach back in I am going to put the 2nd green one in.
That's my take on the 1 red and 2 green lens. FWIW
