Hello,

I have moved house and I was changing some of the light fittings and
light switches to prettier ones. I was surprised to find that
downstairs the lights are wired with stranded wire. I hadn't seen this
before. The colours were unusual as well: one light switch had red,
blue, and white. What wire is that? Should it be rewired in standard
colours and cable do you think?

There's also a loft conversion but the lights and sockets all seem to
come off one FCU. That seems strange. Couldn't they have kept the
lights separate to the sockets by going off the first floor lighting
circuit?

Thanks,
Stephen.
