I am trying to wire 2 wall lights to a porch in my house. I have wired them up correctly but dont know how to connect them to a circuit. I have put a new switch for them next to the up and downstairs switch. I have drilled holes in the side of both switches and fed wires from my new porch lights into the existing up and down switch box. i have tried a few combinations as i have no idea were to put them. some dim some lights some do nothing. do i need to get a different new or old switch to wire them in, as i have just been adding, which is overloading more than likely? any advice would be great thanks.
