What was connected to the ceiling box before?
What color are the 2 wires in the new fixture?
Is one of the fixture wires ribbed?
Customer: replied 7 years ago.
A light fixture, 2 clear wires from the new light fixture and a copper wire, no none of the fixture wires are ribbed

Does the ceiling box have conduit or cables that contain these wires?
Is it correct that you have 1 red and 2 white wires, no other colors?

whats the difference? it has red, white, and black coated wires, and a copper wire, ... the light turns on from 2 switches

Expert:  electrifier replied 7 years ago.
First you had red, white and white wires, now it's red, white and black. Which is it?
The difference is important. If it wasn't I would not have asked the question.
Before I tell you to connect the 2 white wires together I need this information. You are my eyes on this. I can not see your light box and am depending on answers to my questions with no mistakes. If you have a black wire with white paint on it from painting the ceiling I must be told the wire is black, not white.
Again what wires are in the ceiling box for the light?
Is it conduit or are they in a cable or 2 cables?

I have red, white and black wires coming from the ceiling. conduit
Expert:  electrifier replied 7 years ago.
copper is obviously the grounding wire for grounding your fixture.
White is the neutral wire and goes to either of the wires in the fixture.
I would guess black is hot all the time and red is switched so if you connect the other wire to the red then try the switch and see if it works. If not let me know. Then we will try the black wire. Put a wirenut on the wire not used for anything so it does not short out anyplace.

the black and white connected to the fixture causes the light to stay on...cannot shut the light off when I turn off the switch.

What happened when you tried the red and white wires? Did the switch work then?
