I am trying to wire several lights on a circuit. I have the source through on light fixture and then connected two other lights and a switch. The switch works and one of the lights burns at full brightness. The other two lights have power; however, they are dim. I know this is b/c they must be wired in series. However, I cannot figure out how to wire them in a parallel sequence so they all get full brightness. Can someone help wit hthis obvious flaw? Thanks.
