I'm sticking with DC for my shelf layout (not sure whether I'm chicken or just cheap). How can I wire my locomotives so that the back up headlight goes on when I reverse the engine? I know there are kits out here, but I'd like to do it with components to save money. I remember doing something with Radio Shack do-hickies back in the Stone Age, but I've long forgotten how to do that. Can anyone help? <br />Thanks, and have a Happy New Year! <br />George
