Green Lights in Mosques

Can anyone enlighten me as to why green lights show from the minarets of the mosques?

This web page Green Light seems to be saying that the green light indicates that the building is a Mosque. I looked at the Wiki page for Mosques and did not see it mentioned, but I admit I skimmed the article.

Just one of those things. A mosque can have green, blue, red or no lights and still be a mosque. I suppose it helps identify the building’s purpose.

The Saudi Arabian flag " is green because green is the traditional color of Islam".
So are the flags of Lybia,,Pakistan (and Islamic terrorist groups like Hamas and Hizbollah)

Plus green is a pretty color, especially for people who live in a place with little natural vegetation.

Like Indonesia.
Seriously though, given what chappachula said, I wonder if there is some connection like that - Islam as an oasis - in green being the traditional color of Islam. Sorry for the hijack, but does anyone know anything about that?

Indonesia’s flag is not green.
Wikipedia blurb:

Nothing to do with the OP, though.

Paul in Saudi presumably knows what he’s talking about.

… to differentiate them from bordellos?
