My second install, pulled the light board and hard-wired an original late-issue BL2 with an LM-2. I left in the plastic board to mount the module and lights. The headlight and rear light are Miniatronics 3mm YeloGlo LED with resistors, shrouded in heatshrink. I added heatshrink tubing to cover solder joints and other bare wire. For neatness, I removed unused wires from the JST plug. The crew figures got some detail paint, as well. Still have some work to do to seal light leaks in the cab, and to add phosphor wire pickups to the trucks. Interestingly, this loco runs better in a consist than alone.
