What is the red wire in 12 3?
12-3 NM (aka “Romex”) cable will have a bare grounding wire, white neutral (grounded) wire, black hot (ungrounded) wire, and red hot (ungrounded) wire.
Can I use 12 gauge wire for lights?
Yes, it is okay to use 12-2 cable to supply lighting fixtures. The other answer indicates that it even with 12-2 you have to use a 15A breaker for lighting circuits which is not strictly correct. If the entire circuit is 12AWG (other than fixture wires), then a 20A breaker may be used.
