Dear sifus,
My room has two light points with one switch. I plan to install 4 downlights with two switches.
Is there anyway for me to not hack the wall for wiring and install new switch (with two switches).
Is there such a thing I can use that, say, if I switch on once, will light up two downlights. Switch off then on once more, will light up all four etc. (Just like some lightings with LED and bulb).
Thanks
