I am having an issue with the new lights not switching off. I installed 2 new lights and wired them into an existing light switch that operates the ceiling light. When I wired the two new switches I connected 3 wires (white, black, ground) together, one leading to each of the 2 new lights and one that leads to the existing switch. When I tested the light switch the ceiling light will come on and go off, but the 2 new lights stay on no matter if the switch is on or off. Right now it seems like the live and the ground wires are working on the new lights, because the lights come on when the power is turned on, but they dont go off when the light switch is turned off leading me to believe that the neutral wire is not working. When I connected the wires for the 2 new lights I connected them the same way as the wires that are going to the ceiling light. How do I get the 2 new lights to come on and go off with just like the ceiling light?
