The beacon is the third most common oscillator (after the blinker and toad).[1] It was found by John Conway in March 1970. It is composed of two diagonally touching blocks.
The beacon is the simplest on-off. Its rotor, known as diagonal on-off, can be supported by several different stators: the two next-smallest are seen in eater plug and 21P2.
As an eater
A beacon can be used as an eater for any even number of gliders, using the boat-bit reaction. When they collide into it as pictured below, the first glider of a set will be transformed into a boat, which will then be destroyed by the second.
Beacon Mover
Three cells placed above and to the right of a beacon will move the beacon 1 cell up and 1 cell to the left after seven generations.
