The reason behind Light's alias

Have you ever wonder why L chose Light's alias as Asahi? Well,some believe it has to do with Asahi Light,a brand of beer commonly sold in Japan and other select Countries,making Light's alias difficult for search engines while also taking the everloving piss. However,some others says that Asahi Light can be translated to Light Morningstar. It is the name of Lucifer's (The Devil)reminiscent,named The Morning Star. This is a very good theory,considering that Light wants to create a new world where he can rule as God.
