The great on-off (or pincers[1]) is a period-2 oscillator. It has the same rotor as the beacon and resembles two welded loops.
Commonness
The great-on-off is the ninth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than the quadpole but more common than the figure eight.[2] It is the ninth most common oscillator on Adam P. Goucher's Catagolue.
The great on-off typically forms via a teardrop hitting a traffic light.
