Electrical Wiring in the Home/Replace lightswitch with LED nightlight/switch combo


I want to replace a lightswitch with a LED nightlight and switch unit. Currently there is black, white and ground wiring. When purchased, I was told it would work. However, another employee said it won't because there needs to be two black wires. Is there anyway to do the job with existing wiring.

The white wire is really a hot wire, and it should be black. This is called a switch loop.

However, I do not know if the unit requires a neutral or not.  If it does not require a neutral, it will work. If you need a neutral, it will not work.  You can look at the wiring diagram. If it shows two black wires and a white wire (in addition to the ground), it will not work. If it shows two black wires and no white wires, it will work. Just use the white wire as a black wire.
