for a while now my two front room lights have run from just one dimmer switch but ive bought a double dimmer switch to put in instead, but i dont understand how the wiring goes: it seems like the lighting circuit starts from the front room:
this is the switch..
i dont understand what the blue, yellow and red wires do...
