Not sure what you mean by "light holes." Do you mean a missing fixture or is the socket missing from inside a fixture?
If the light fixture is no longer on the wall, you need to replace it. If the socket, internal to the fixture has been pulled out, you also probably have to replace the bad fixture with a new one.
In my experience, there is no way to replace a "socket" in a fixture.
BTW, welcome to the site and your question does make sense. If you could post some pics, it would really help. ANY question is OK here, except those dealing with the meaning of life, why dark matter exists, or exactly what year the San Diego Chargers will win the Super Bowl.
