Thanks again Stan and John for this idea. 49 amps; holy smackers! Those should handle things easily. I think I will go ahead and test those mosfet's and see how it goes. Just ordered some, only a few for testing for now. I will do that 0-12-0 volt swing testing on L1/L2 first Stan, and see where that takes me.
John, no I don't need to flash the LED's also. The original basic board with the 8050's will work for the LED flashing task as is. Just wanted to morph the basic board into something that I can use for flashing much larger LED bulbs for another task, so the LED's can surely be eliminated.
Next project will be to revise my schematic and put that up on here for all to critique.
Thanks, Rod
