How do you wire two light fixtures?

The lighting fixture should have all of the bulb's leads brought to a central point in the fixtures junction box. All of the black wires from the bulb's socket will be tied together. The same applies to the white wires from the socket.

The white wires are tied into the lighting circuit's white neutral wire and the black wires are all connected to the "hot" supply wire. Once these connections are made, the fixture can be bolted to the ceiling junction box.
