Hello everyone! I am new to the forums (and for that matter, anything DIY). I have to apologize for my newbie-ness, but I want to make sure I do tthis right. I have decided to replace the light fixture in my bathroom, and watched a couple of youtube videos on how to do it. Anyway, I managed to take the fixture off, unhook the wires, and unwrap the new fixture - then I got cold feet. In the new fixture, there is a white wire (which I have learned is neutral), a black wire (a hot one), and a bare copper wire (the ground wire). Cool. Inside the wall, there are two white wires attached together, black wires attached by a cap, and a red wire! I think there is also a ground wire, buried in there somewhere. Eek! I am a wee concerned, I don't want to blow up anything, so what should I do? I'll also see if I can take a picture with my phone so you can see what I mean. Any and all help is appreciated - I am trying to surprise my new husband while he is gone away with his job. Newlywed enthusiasm!!!!

I am finishing my basement and have full acess to the ceiling. I want to install IC recess light cans and I know it is pretty straight forward - put the bars flush with bottom of the floor joists and you're all set. Problem is I have strapping perpendicular to the floor joists for dry wall support/nailing (I think they are 1/2" thick). So, with the 1/2" strapping plus abother 1/2" dry wall, isn't the opening of the can too high (or too deep from the bottom of dry wall) for the trim to fit? Isn't the trim suppose to go all the way? Thanks in advance.
