Thanks ricm, All that info. helps! I have been looking for more opto couplers and was getting no where fast for a higher output. The #4N25 will help, I'll look into it. I was almost going to ditch the idea but it's no good if the lights are just running lights, takes away from it all. Now to figure out how to hide all the wiring. I'll work it out.

Much thanks to both you guys!!
