The BR 425 on Bremen - Oldenburg has some serious problems with it's headlights. The biggest issue is that the normal signal lights aren't working at all. You can see this here: The tail lights (off position) are way too bright and appear yellow / white although they should be red. The hue is correctly red but that's also too strong. This is also a problem on the double 425s. The way too bright tail lights even shine into the opposite cabs. Also I think the tail lights shouldn't even be switched on between units. The high beams are supposed to also have signal lights on as far as I know but I might be wrong there. At least it's that way on the HRR BR 425.
I can confirm, the switch positions are reversed, "Marker Lights" position = marker lights off and "Off / Tail Lights" position = marker lights on but they are shining red, it's not possible to switch on the red tail lights itselfs.
No those aren't marker lights, they are white tail lights with a red hue and the top light also doesn't show. So it's not reversed, just parts of it are broken.
after doing gameplay of it on PC Steam with my Launch Livestream its a clear issue the DB BR 425 Back of Trains lights should be red and they not and u can only use high beams to have lights on front its once again Dovetail not checking everything over and shows how much they care about getting everything right so much for this so called new system to check issues before getting the final tick
