hi. I had my garage converted about 18 months ago and had it set up for outside lights also. I have just eventually got around to putting my outside lights in and then only work when the garage(bedroom lights is on) the bedroom light switch is 1 way with L in com and N in L1 the light switch for the outside wall has a L and a N and then there is a wire that runs behind the light switch and continues up the wall to maybe a junction box in the ceiling? this wire runs outside the the outdoor lights through conduit and under my slabs. so I connected the outside lights and they turn on and off fine but only when the bedroom light is on. has a live and a switch live been mixed up in the ceiling area somehow? I cant get to anything due to the conversion so not sure on what to do to make the outdoor light switch work independently.
