Under Kansas state law, when a traffic signal is completely out of service, drivers are generally required to treat the intersection as an all-way (four-way) stop, unless a law enforcement officer is directing traffic or another traffic control device indicates otherwise.
This means:
Come to a complete stop before entering the intersection.
Yield to vehicles that arrived before you.
If two vehicles arrive at the same time, yield to the vehicle on your right.
Proceed only when it is safe.
This is different from a traffic signal flashing yellow, which requires caution but not necessarily a stop.
Important legal distinction: Kansas statutes K.S.A. 8-1508 and 8-1510 address operating and flashing signals, but I could not verify an explicit statewide statute stating that every completely dark traffic signal legally becomes a four-way stop.
