If this is the only light that goes on with the switch, what you have in the
box are one feed, bringing in the 120? volts, one line bringing the 120?
volts out to something else, and one cable which goes to your switch. Once
you determine which is which, you should have two white wires together which
will also connect to the white of your fixture. You'll have two blacks
together to which you will also attach the white wire to your switch and
wirenut the three. You are left with one black, which is the return wire
from the switch and this will go to the black of your fixture.

I have a bit of a dillema with my bathroom lighting. I am trying to
install a new light above the mirror but i just can't seem to get it to
hook up properly. The existing light worked and I was positive I saw
what was already hooked up and did the same with the new light. I have
black to black and white to white, but still nothing works. The concern
that I have, and which is more than likely the case, is that I am
attaching the wrong wires. There are three sets of black and white
wires comig out from the back of the lighting panel. If you picture the
octagonal box facing you there are to sets of wires on the far left
(which is closest to the wall with the light switch) one above the
other, and then the last set of black and white wires are located down
towards the bottom right corner of the oct. box. THe white wire from
the bottom right one is left open whereas the other white wires have
been merretted together. My problem lies with the black wires. Since
there are three of them exposed I have tried connecting the black wire
from the new light to each one of them and still no luck with power. I
hope I have explained everything ok, if not I will try to give as much
clarification as possible if anyone is willing to help.
