On April 1998, a variant of the Game Boy Pocket named Game Boy Light was exclusively released in Japan. The differences between the original Game Boy Pocket is that it takes on two AA batteries instead of two AAA batteries and has a backlit screen that can be turned on or off. This backlit screen allowed the use of it in darkened areas. The Game Boy Light was superseded by the Game Boy Color six months later and the Game Boy Light was the only Game Boy to have a backlit screen until the release of the Game Boy Advance
SP in 2003.
