I currently have an outside light with a single pole switch, what I want to
do is install another outside light over the garage in series with the
existing light and switch and also add another switch in the garage to
control both lights.

I have found some schematic on the web but I want to sure before I attempt
this that I have the correct information. I believe what I'm installing is
the typical circuit that you would have for a hallway light that is
controlled by two switches.

Any info would be great.

Thanks
Steve
