In fairness, a picture does help. Straight way it can be identified in some way.
a) (unlikely) a standard fit Honda thing. As that would of showed up as something in your scour. (And I've seen it loads of times on forums where people claimed to have searched for something and haven't)
b) an aftermarket switch someone might have a clue as to where it is from, or what aftermarket kit it may have been supplied with.
c) you don't say what sort of switch it is (a rocker/toggle/push/etc), only the colour.
Your second ever post of "sarkiness" does come across plain rude and arsey. It's not as if you've been posting here since nineteen canteen and we understand the intended tone of your emoticon-less post. Also a very clever ploy that to lose most of your potentional respondees.
Anyway, good luck in finding the function of the green switch fitted to your car. I'm out.
