How to make the light turn on every other time?

Good afternoon. Question: There is a small light on the chandelier and there is a main light. Single switch. Scheme-work cycle:

1 press of the switch - the main light comes on;

2 pressing the switch - everything went out;

3 pressing the switch - both the small light and the main light come on;

4 pressing the switch - everything went out.

How to implement this? I suppose that in front of a small light there is some element that passes current through time. Tell me what kind of element is this Thank you.

    Hello! There is no such element that passes current through time. A similar circuit can be organized by a pulse relay to control lighting. Here as shown in the picture.
    Such circuits are released by microcontrollers, shift register logic circuits, and other circuitry solutions.
