The updated version. The lights have three states instead of two.
Similar to the original except that lights can be red or green, so it has 3-colour puzzles (red, green, off). Repeatedly pressing a button changes a light and the adjacent lights from off to red to green and back to off again. There are 100 built-in puzzles. It also allows you to play the classic 2-colour game, with 50 built-in puzzles, as well as an action game and a 2-player game.
