Just started work on rewiring the original light housing on my Bennett 543. Have not done this model before. I have two questions-

1) I have removed all the covers and only have the porcelain socket to get out. How do I remove it? Does it somehow screw out? I don't see any other way.
2) My pump has never had a globe on top. So there is no existing light socket on top. However, when I removed the top of the light assembly there is a porcelain socket hidden under it! Is that somehow supposed to be used for the globe? See the picture I posted.
