I have a new exterior wall light to fit,
Can i fit it directly via my vestibule light switch by fitting a new double switch ? ( 2 x L1,L2,comms ) replacing the single switch that is there at the moment.
wires in light switch are 2 red live and an earth attached to box in wall
and wires in external light are red live ,blue nuetral and earth (yellow/green).
I know that both earths are attached to box in wall and that the live goes to one of the comms with a short piece of live between 2 comms.....
after this i am puzzled as to how or where i place the blue nuetral from the external light.....any help from any of you experts would be greatly appreciated
