Hi,

I am replacing my medicine cabinet in my bathroom. The old medicine
cabinet had the bathroom lights built-in to it at the top. My new
medicine cabinet has no lights so I need to install some lighting above
it.

My question - the wiring for the light needs to be extended by a foot
or so. It is too short to reach where the new lighting will be
installed. I have never done electrical work -- is it as easy as just
buying a small piece of wire -- hooking up the black, white and copper
wire ends of each wire?

Please any help is appreciated. You can assume that I know nothing
about wiring - I will not be offended by very obvious things being
explained.

Thanks,
Joe
