Why not put your bedside lamp on a different house code from the other
lights then you can use "all off" to turn off all lights except
the bedside lamp.

LD10's are in the wiring closet (if you can call it that) i wanted some
kind
of visual indication as to the status of the LD10's so that instead of
wandering round the house to see which lights are on i could pop my head
round the door of the wiring closet and switch them on/off with the RF
remote, Its mainly to make sure they are all switched off before i go to
bed, i dont want to issue the "all off" command as my bedside
lamp is also
x10 and i dont want to stumbling about in the bedroom waking up 'she who
must be obeyed'  its taken me ages to WAF for x10 stuff so i dont want to
go
rocking the boat :)

I have seen a modification to an x10 light switch of somekind and was
hoping
to do a sinilar thing, i believe it was a US model though so 110v....

I thought of that almost as soon as i hit the send button :)
But would a neon "dim" when i dim the lights ??? (LV transformer)

Many thanks for the advise Keith, much appreicated
