Does this sound like incompatible LED lights, bad wiring or do I need to buy new matching 3 way switches for them to be compatible? I am 80 miles from the store I used (or have to buy from Amazon) so I want to avoid back and forth driving.( Old regular 3-ways are Ideal 56-002A.) This is old wiring with no ground.
