Security light issue

[Mike spear]

Hopefully someone can help me with a Pir security light problem I have. I fitted a new Pir light on the front of my garage the other day and found that the existing supply cable is a 4 core jobbie (brown, black, blue and yellow/green earth) and inside the new lamp there's just live neutral and earth connections. I tested the wires and found the brown wire was delivering 240v and the others nothing, so I clipped and taped the black wire and fitted the others. The light works perfectly - unfortunately there are 2 other auxiliary lights on the side and back of garage which were activated when the old Pir was triggered and these are no longer functioning at all. Where should the black wire go to remedy the problem? Any help would be gratefully received. Thanks guys.

Obvious question is what was the black connected to originally?

Do you just have one cable at this light?

Do these lights have an override switch?

Where are the other light wires connected? Photos?

That 'blue' is probably grey.

.... and inside the new lamp there's just live neutral and earth connections.

Unfortunately, if your new PIR light only has L, N and E connections, then there probably isn't a way to achieve the previous functionality (at least, without playing within the works of the new light). The '4th core' is presumably intended to take the PIR-switched output from this light to the two auxillary lights - but it sounds as if your new light may not provide such an output. Are you sure that there is not a fourth terminal (in addition to those for L, N and E) in your new light?
