I got this idea recently, and i think that it's possible.
A green light, a little bigger than the player light and only the one that's using it can see.
It'll be easier to hide in dark maps without to others to see the player light etc.
So it's basically a light that isn't showed to the other players. I would like it to be a item that you pickup and using that way. /Opinion
Is this possible? If it is, i would really like it.
