All you have to do is take the light out, disconnect the feed wire, get a length of suitable cable with a male spade connector and plug it into the feed female spade connector, route the cable to where you want it and connect to the switch, Then take another length of cable and attach to the load terminal of the switch and then route back to the light ( obviously these steps would be done with suitable twin core cable), Connect a female spade connector onto the cable and then attach to the light. All you have effectively done is put in an "inline switch" Then just repeat the same for the other light. The switch I put the link for has a double pole, so it has 4 terminals. 2 feed and 2 load terminals so you can run both lights from the 1 switch but keep them separate.
Hope that makes sense !
Perfect sense - so no wires cut, only spade connectors removed & extra wires and a switch put in place. Might try that
