I have florescent light in my bathroom that I would like to replace
with a incandescent fixture. The transformer is attached with 2 wires
( red and blue ) which is going to a toggle switch that turns on the
light. I am confused with the blue wire...I've seen black, white...but
never blue. Why the blue? Does it replace the neutral White? BTW,
there is also a outlet plug next to the toggle switch.
