i would like to add another outside light. Curentley have one at end of house and would like another on same side but other end, I am planning on taking a 1.5mm cable from my existing light (the connection block inside light) to the connection block in my new light. The main feed is from a switched FCU with a 3 or 5 amp fuse in (not had time to check) but i know that the fcu is spurred of one of the sockets from ring main. the existing light and the new one have there own built in PIRs, with the power feeding the new light coming from the old one, will the PIR on new light still work on its own? any advise is welcome thanks.
