Why does my ceiling light have 4 wires?
The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.
How do I wire another light to an existing light and switch?
You can usually install a light fixture between an existing one and the switch by cutting the cable to the existing fixture at the location of the new one, inserting the ends of the cable into the electrical box for the new fixture and pigtailing the new fixture onto these wires.
Where do you connect an earth wire to a light fitting?
The earth wire or neutral should be connected to the shell of the lamp holder. The hot should be connected to the center contact of the lamp holder. The reason for connecting the earth wire (neutral) to the shell is so you don’t make contact with the hot while removing or installing a lamp.
Can you install light fixtures yourself?
No need to research your particular situation other than making sure the size of the fixture itself fits okay in the space you’re putting it! In general, you can go out and buy any light fixture, and put it up in your home where any light fixture already exists.
Can you replace light fixtures yourself?
You’ll need some basic electrical skills to replace a light fixture. Once you know how to replace a light fixture, you’ll be able to tackle a variety of other relatively easy projects, like replacing an outlet or light switch. As with any electrical project, caution is the rule of the day.

Why does my ceiling light have 3 wires?
The 3-wire system is less common than the 2-wire system, it includes a Neutral at the switch as well as the Live and Switched Live wires. One ‘2-Core + Earth’ cable takes Live and Neutral to the switch back box, a second cable takes the Neutral and Switched Live to the light.
Why is there a red wire in my light fixture?
The exact purpose of a red wire for a light fixture can vary. Except in rare cases, it is a hot wire or a switched hot wire.
