I am replacing an older style vanity light in a guest bathroom. The old light has a convenience outlet built into the light fixture base. The new light has only a black, white and ground wire. The painters removed the old light so I do not know how it was connected. The wires coming from the box are: 2 white wires connected together and capped, 2 black wires connected together and capped, and one red wire. I have tried to wire the light as follows: Capping the red wire and connecting the white from the new light to both whites from the box; connected the black wire from the light to both black wires from from box. When I do this and turn the power back on, the light stays on all the time, i.e. turning the switch on and off does nothing, the light is always on. Other info: the switch in the bathroom has two switches, one which operates the light and one which operates the fan. How do I wire the new light to the existing wires? Donna

From the wall use the whites as you did before but use the red to connect to the fixture black wire.

Dear Stanfortyman - followed your instructions and the installation is complete and the light works as expected and looks great. Many thanks for keeping me safe in the electrical world. Donna
