Hello,
I got a Lionel Legacy NS 9811 Non-powered Dash 9 SKU: 6-28300. Since it’s an older legacy engine it has incandescent lights for the cab and number boards. I’m wanting to change them since all my other engines are led lights and I like the look more. I wired LEDs from Lionel’s parts site in them and tested but they flickered and was shorting out. I’ve converted to LEDs in passenger cars before but never for a locomotive. Do I need a resistor for the LEDs or something else? I think the incandescent bulbs run off of track power and the wiring for them comes from an electrical board.
Thanks
