I have a two way lighting circuit controlling two double tube-lights in a shop, the back and the front. I would like to change this system to spot lights at the front (aprox 16, R50 40w) lamps at the front, and the back remains the same. I want the switch at the front to only control the the front and the back to only control the back. At each switch the common has a yellow wire, L1-blue and L2-red.
