The Passenger Car LED Lighting Kit includes everything you need to light two cars, including the regulator boards.
@SteveMa posted:I'm confused, are there only certain passenger cars that cause this impact that require modification?
Usually, it's circuitry in the car with capacitors across the power that degrade the DCS signal. Without knowing specifics of the cars, it's hard to say why these cars affect the signal.
Truthfully, almost anything on the tracks has an effect on the DCS signal, some car and engine configurations just impact the signal worse than other configurations.
