Is the red connected to the switch?
Did this used to be a setup for a ceiling fan?
Assuming this was a setup for a ceiling fan, you will need to connect the smooth lamp wire to the red ceiling wire. Connect the ribbed lamp wire to the white ceiling wire and cap the black ceiling wire securely with a wire nut.
If the black wire is connected to switch, then connect everything as stated above, but use the black wire instead of the red. Just cap the red wire at each end with wire nuts.
