One lamp is connected across corresponding phases of two alternators. They will be synchronised when
- the lamp is extinguished.
- the lamp is either at maximum brightness or is extinguished.
- the lamp is maximum brightness.
Explanation from PART66Online
With a lamp connected across corresponding phases of two alternators (the dark-lamp method), the lamp goes out when the two phases are in step, because there is then no voltage difference across it. Synchronism is therefore indicated by the lamp being extinguished, not by maximum brightness, which indicates the phases are in opposition.

The lamp shutted down because when two generators are sincronized the amount of current produced by two generator is the same so there isn't any residual current in the circuit. Bye
