Does the vision of uncontrolled wiring put you off adding LED lighting to your layout? Is should!
However, it needn’t, not with the Dwarvin Lamplighter system in which there is no wiring needed - the use of fiber optic lighting avoids all this. Imagine, no wiring, no soldering, no tangle needed! Just mount the Lamplighter box, drill a hole and insert a fiber.
Thanks Rick Wilson for kindly provided me with this picture of the back on his control board.
