The LED lights of my K-track bumpers (Maerklin 7389 Prellbock) flicker. They are powered by a booster which serves only accessories like turnouts and so on. How can I prevent the flickering?

You say you are powering them from a booster, which to me means you are using digital power. I would power them from a separate lighting transformer/circuit and make sure that the brown wires are joined between the lighting and booster circuits. The bumpers only have one wire which connects to the lighting circuit and the return goes through the rails that are connected to the brown "O" power connection.

That is what I have on my layout and do not have any flickering.

What was I thinking? I power them now from an analog transformer and the lights are right on.
Thanks,
