Hi @adamvb, just out of interest, is it the white end lights that are flickering when the DT is in reverse, or is it that the correct lights are on but are flickering in general?
The end lights on my DT work perfectly well when running forwards (i.e. push mode) but when running in reverse (i.e. pull mode), the red lights work fine, but the white end lights flicker and occasionally as does the destination board (which is mostly off when in reverse and on running forwards - I’m unsure if it is meant to be on in both directions). I have already emailed the Accurascale support team so hopefully there is a solution.
