I am replacing two light fixtures in bathroom, they are on one switch. First one went in as planned, black to black, white to white. The second one, closest to switch, however is not looking normal. The wires came off the caps as I pulled old fixture off (screws were bent and force was required). I have two white wires twisted together, they appear to have black ink dots on them (hot perhaps?) and just a copper ground wire. There are also two black wires capped together and farther into box, I don’t think these had a wire attached to them as only two caps were loose, and the black attached together wires were pretty far into box. Issue is, if the white twisted together wires with black marks are my hot power source, and I attach black fixture wire to these, what do I attach white neutral fixture wire to?
