Traffic light
The traffic light is a common formation of four blinkers and is the most common member of the familiar fours, also being the only one made from oscillators. A common predecessor is the T-tetromino. Although it behaves the same in some important non-standard rules such as HighLife as it does in standard Life, it does not appear nearly as frequently in many of those rules due to its common predecessors being unstable.[1]
