Turn the power off to the circuit first at your Breaker/Fuse panel. Once you know that the circuit is dead, remove the old fixture.
One of the 2 wires goes on the black, the other on the white. If there's a bare ground, ground that to the junction box where the fixture is going. Secure the fixture in place with the provided hardware, and turn the power back on at the breaker/fuse panel. If you did something wrong the breaker will trip/fuse will blow.

First, identify the positive and negative wires of the dome light. Typically, the positive wire is red or black with a white stripe, and the negative wire is solid black. Connect the positive wire to the power source and the negative wire to the ground. Use wire connectors or soldering to secure the connections.
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches. At the switches, connect the red wire to the common terminals and the black and white wires to the traveler terminals.
Disconnect the fixture wires and remove the central mounting nut to release the dome from the light fixture in a ceiling fan.
To wire a three-way switch with SPDT switches for one light controlled by two switches, you will need to connect the common terminal of one switch to the hot wire coming from the power source, connect the common terminal of the other switch to the light fixture, and connect the two remaining terminals of the switches together with one wire. This configuration allows either switch to control the light. Be sure to follow proper wiring techniques and safety precautions.
Yes, you can tap into the three-wire cable to add a light in the closet. Identify which wire is the hot (black or red), which is the neutral (white), and which is the switched hot (usually the red). Connect the hot wire to the light fixture's hot wire, the neutral wire to the light fixture's neutral wire, and the switched hot wire to the light fixture's switched hot wire. Ensure proper wiring and use appropriate safety precautions.
Having two black wires connected to a light switch indicates that it is a switch loop, where one black wire brings power to the switch and the other black wire carries power to the connected light fixture. The two white wires capped off are neutral wires from the power source and the light fixture, which are typically not connected to the switch.
