Hi, I have a track lighting fixture that is finished on the ceiling, and I can't see what's in the box as it is behind the drywall. I am putting new drywall on a wall below and want to add two wall sconces to that circuit. The wall being refinished also has the light switch for the above track lighting plus an outlet (not-switched) that terminates there. The power goes into the track light first, then down to the switch 12-3 wire. I removed the outlet as there is another too close and on the same wall but different circuit (always seemed odd to me). The wires in the track light connector are red, black and bare ground. The original wiring on the switch including the non-switched outlet had: Red to the top screw of the switch, black to the bottom screw. The black also went to the non-switched outlet. White with black electical tape ring (which I believe is supposed to indicate alternate use) comes from the fixture. That white is capped to the wire going to the non-switched outlet. The non-switched outlet is now removed from the wall. The original switch is pulled from the box as I want to add a dimmer. Going out of the switch I added 14-3 wire to the first box for the wall sconce (I wasn't sure at the time, but I think I could have done 14-2 on this as well). From that box to the next box is 14-2 wire. So what I want is the new replacement track light, and the two sconces to be on the dimmer switch. But I believe I will have an extra wire in the mix. Should I have the red and black from the switch go to the 1st sconce. And since I put 14-3 on the new wire going to the first sconce, what colors should I use going out? Also is it safe to cap/tape off that white wire with the black tape marking on it? Thanks.

I am putting in recessed lights in family room of addition. I laid them out approximately where I want them, using cooper lighting guide. I found center of ceiling and put one there and then was trying to space about 5' apart as per the guide. But plumbing got in the way. If I move one light so not in that bay, I have to move another (for symmetry) and it then will be below plumbing. So, is it OK to have a recessed light below plumbing drains? I have HALO H7ICAT 6" cans. they are IC rated and air tite. why am I using these in living room? Cause I planned to put insulation as a sound barrier. The plumbing in question is actually a short run of the main vent, just before it hooks into the toilet drain. The can would be near the elbow where the vent comes down and there is about a foot of horizontal run away from can to the location where toilet drain is located. The can would be about 1/4" from contact with pipe. I have another one that is also potentially going to be very near my tub drain, but won't know for sure till plumber gets it hooked up. could it go right below the drain? by the way, these cans don't work great for 16" on center wood I joists. The slider bars are too long to get in way since the open space between the joist is less than traditional 14 1/2" for sawn joists. I have to cut them which is a pain.
