I would like to put up an outside light that can be operated by manual one gang switch and PIR circuit. I have knowledge of how to switch it conventionaly, but unable to understand how to incorperate the two? do I need to invole a permanent 2nd live to the light here?

yep so you need a three core and earth cable going to your light one neutral one permanent live and one switched live.
ps. just thought...most sec lights now only need the switched live coz you just leave it on for normal operation or switch it on and off within 5 secs for it to stay on.

I have two external PIR security lights fed from the fuse box inside the garage, to a switch (for normal operation and always on) then onto to the first light and on to the second light. The first lamp needs replacing coz the contacts have corroded and burnt out.
I've bought a new lamp of the same spec but the wiring seems to be different!
The existing lamp put two reds, two yellows, two earth and to blues into the four terminals in the block.
The new lamp has four terminals which have different contact cables coming from the other side of the block.
1 - should I be using three core and earth, and
2 - where do the red, blue, yellow and earth cables go.
The instructions do not cover 3 core & earth.
