Hi there.
First time enquiry for me. I have just installed a PIR controlled security light in place of a very old normal, switched outside lamp. I have re-used the original wiring feed to supply the new lamp BUT...the original wiring is only twin core (live & neutral?) & the installation instructions for the new lamp state that it requires an earth. Is this for functionality of safety? In other words, if I leave out the earth should it still work but not be safe in the event of some internal failure? or will it not work at all without an earth. The fact is, having fitted it, with just the original wiring in the live & neutral points, it doesn't work.
This is a very old house & the wiring is just as old. Here's an idea of the age; many ceramic fuses still functioning & circuits are fused on both the live & neutral sides!
