Thanks in advance for the help. I'm sure this is a simple solution but just something I want to get a second opinion on. I replaced a light fixture in a bedroom. The receptacle box for the ceilng light was wired with a single 14-3 romex, set up for a ceiling fan I guess, but no fan present. I also installed a single pole switch at the switch. At the switch, there is only a single cable of 14-3 romex also. At the ceiling fixture, I connected ground to ground, white to white and black to black, capped Red in the box. At the switch I also capped Red in the box and attached white and black on the switch on the two copper screws. Switch works as it should and light functions properly, on and off. Here's what is causing me to second guess though. I opened the switch junciton box and when I flip the switch, my non-contact tester is reading hot on both the red and the black wire, even though the red is capped at both ends. Did I do this correctly? This is the only switch that controls the light source. I did not test voltage on the red wire in the ceiling box.

I've been told by an electrician that in order to add an exterior porch light, he needs to run a long wire and put a junction box, etc, etc. it seems so uneccesary to add one small LED light (5watts). There is a small bedroom on the other side of this exterior wall with an outlet just below where I want the light. It's on a 15 amp breaker. Is there a reason why I can't tap into that plug and use exterior wire run up behind the siding and power this light? I don't want to do anything unsafe of course and I don't live where codes are an issue but I still want to be safe. Thanks for the feedback.
