My newly acquired Lionel Covered Bridge does not illuminate. I originally thought that the 3 lights in it were incandescent type. When I opened the accessory to troubleshoot, I discovered that there were 3 LEDs. I connected the two leads directly to track power; using a KW transformer. Do the rectification circuits not handle the conventional sine wave output or does it nee the square pulse output from a new transformer? Can anyone shed some light (pun intended) on why the LEDs don’t work. Also, do LEDs have a constant illumination above a threshold input voltage? – that is, if on track power, illumination won’t vary with change in voltage? If the LEDs can’t run off conventional transformer, then what can be done? Alfred By the way, in the meantime, I am installing two screw-base light sockets and running incandescent off auxiliary power.
