I was wandering how you would wire red and green leds on a panel to show how a switch is turned under a mountain; I know switches under a mountain is a no, no, but had no choice without a lot of modification. I have atlas and peco under the table switches. What type of Leds do you use; how do you wire them; and do you have to use resisters; and what ohm resister would you use? A lot of questions but I thought I would as the experts, especially Jim Banner. Hope to get some good ideas. Thanks for your input. Larry
