I was changing the light fixtures already installed in the ceiling.
These are several lights on a 4 way switch. I did not go near the electrical box or change anything in the light switches themselves.
When I was disconnecting the old fixture I notice that there 2 sets of wire feeding into it and one feeding out into the next light fixture... I thought this was odd but thought that the extra set of Black White and Copper wires were due to the lights being on a four-way switch. To my surprise when I turn on the switch now, I can turn on my porch light. This light fixture has it's own light switch right next to one of the hall light switches but was not controled by the hall light switches before (there are 3 switches to turn on and off light switches in hall) Now I seemed connected them all together.
