Which wires go where in a light fitting?
If the light fitting you have purchased has just two cores – live (brown) and neutral (blue), connect the live to the switch live terminal and neutral to the neutral terminal. If the fitting has an earth core, it must be sleeved with a yellow and green coat and connected to the Earth terminal.

How do you wire a second light to an existing light?
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.
How do you wire a light fixture with two wires?

Why do some lights have 3 wires?
The 2 wire source feeds to an adjacent switch for a different light which then feeds this switch with 2 wires. The switch in question is a single pole. From it, there is 3 wire cable that leads to a light which then connects to other lights controlled by their own switches.
