Is it possible to get a Green Light?

Question

I saw in a house thisGreen Light. I asked some friends but we don't know where it is from. Does anybody know where I can find it? 

Answer 1

It was obtainable from NPC Gaberiel for about 2 weeks since May 31st 2014 as a token of appreciation, once Tibia was greenlit on Steam.
