So what was the white coloured wire in the original problem?

Paul, October 2010

I have just bought a ceiling light and I am confused by the wiring, old property.
On the light it looks straight forward brown(live) green/yellow(earth) and blue(neutral), Simple if the colours corresponded with the 3 wires coming from the ceiling!!!
From the ceiling I have 2 x black wires and 1 x green wire, 1 black and the green are in a poly block (separate) and the other black was not used on the old light (the old light was just connected by 1 white wire from it). Hope this makes sense.
The light will be controlled by just one light switch.
Any idea what way to wire it up?
Be great if anyone can help.

The Old Red = The New Brown
The Old Black = The New Blue
Simple!
If you didnt know that i really dont think you should be changing a light switch around You could end up killing yourself.

Brown is the old red and blue is the old black,Brown/red is LIVE!! Blue/black is neutral,Green is always earth(that's the safest of them all)

Old Red = New Brown
Old Black = New Blue

Same as the colours in the flex that hangs from the ceiling roses
