How do you wire an additional light to another light with a switch?

Answer 1

In the wall switch box you should have a white and black pair from your source of power (120 volts). The other pair of black and white wires from the wall box should be going to the light fixture junction box. With the power off, connect the two white wires together with a wire nut. Connect the two bare copper ground wires together making sure that at least one of the ground wires goes under the green screw in the switch junction box. Turn the switch to the off position, no little indicator bump showing on the switch toggle lever. Now take the black incoming hot wire and put it under the top screw on the switch. Hot wires always go to the top of switches. Now put the black wire that is going to the light fixture under the bottom screw. Tighten both. Install the switch into the wall box with the switch handle in the down position. All switches when installed must be off in the down position. Install the switch plate cover.

Answer 2

To wire an additional light to another light with a switch, you would connect the hot wire from the existing light to the hot wire of the new light. Then connect the neutral wires together. Finally, connect the ground wires together. This creates a parallel circuit so both lights can be controlled by the switch.

Answer 3

Going for the switch to the fixture; there should be a "switch leg" colors will be orange yellow brown or purple purple is normally a travler but you never know :P Hook up the hot ie black red or blue to one side of switch and the "switch leg to the other side of the switch that's it for that...Now at the fixture there will be the same color switch leg where you will hook up the power to the actual fixture there will be two or three wires coming out of fixture hook white to white and whatever color your switch leg is to the black coming out of fixture and ground to ground if so used the ground will be green in no ground going back down to the switch then on the mounting bracket there should be a green painted screw strip the green wire out of fixture rap it around the green screw and then tighten it down and there your hooked up!!

Answer 4

The black and white wires that go to the switched light should be wired in parallel to your new light if possible. There should be wirenuts on the existing light making the connection to the light. There may also be a bare ground wire. Using the same size wire, likely 14 AWG, connect the new light wire to black, white and ground of existing light.

Answer 5

If you want to control the new light off of the existing switch then connect a black wire from the new light's black wire to the existing light's black wire and the new's white to the existing lights white wire and grounds to grounds.

Or if there is no existing light; connect the black wire from the new light to one terminal screw on the SINGLE POLE switch (but not the green grounding terminal) The other terminal on the switch is connected to a black, hot all the time, wire which is paired with a white neutral wire that will connect directly to the white wire on the light. Grounds to grounds. Use 14/2 with ground wire on 15 amp circuit breakers and 12/2wg wire on 20 breakers.

Answer 6

Run a wire from the light to the switch. At the light connect the black power wire to the black wire to the switch. Not wrap some black electric tape at each end of the white wire going to the switch (This indicates that the wire is potentially hot and not a common wire).

At the switch connect the black wire to one side of the switch and the taped wire to the other side of the switch. Connect the ground (bare) wire to the green screw on the switch.

Now at the light connect the taped white wire to the black wire feeding the light and connect all grounds together with a wirenut.

Answer 7

Using a light as a power source has its draw backs. The new light and switch will only operate while the, light for a power source, is turned on. What really needs to be done is to find a unswitched source to power the new light through the new switch. Look for near by receptacle for this source.
