Trying to change light fixture in ceiling. The ceiling has, what appears to be a black n white line twisted together and a red. The new light has a black, white ground. What goes where!? Power is off on the outlet.

Connect the new fixture just like the old one was connected.

Connect the new fixture just like the old one was connected.Exactly!

Why would you change anything?

Exactly!

Why would you change anything?

Thank you for answering- snarky attitude not needed. And you can't the old light had two white, two black and the grounding wire was placed in foam to ground it. The new one has a red, white, black and no foam. The ceiling has a red and a black and white complete intertwined. However, after research on electrical currents and engineering of buildings- I figured it out.

The new light has a black, white ground.

The new one has a red, white, black and no foam.
Why the inconsistency?

In correct input leads to inaccurate responses.

Incorrect - there is a significance to the black, which could be hot, and a white intertwined. Regardless of what existed before. Ask then don't assume.

What's incorrect? I merely quoted you and pointed out inconsistency in your post. I assumed nothing. I know the wiring.
Talk about attitude.

I was merely stating that you would connect the new one just like the old. I see now you are hung up on colors.
Also, in the OP you said the new light has black and white, just like the old one. Now you are saying it has red, black and white.

Glad you go tit figured out. Hopefully I don't get yelled at again.

Stan,
If you bury your ground wires in foam to ground a fixture I'm going to yell at you.

Black and white together in the ceiling would normally indicate a switch loop. A separate red would typically indicate a second circuit or a 3 way switch. However, you can't have a functioning light without a neutral, single white wire somewhere, unless it is a series wired light. So if you figured it out, whàt was the solution?

Yes, no rationale to a. "ground " wire buried in foam??
