In reality, when two ICE 3s couple, the headlights automatically turn off, which you can perfectly see here: source in TSW however, they are still on, Zg0 to be more specific There are a few overall issues here and there, I'm just gonna list them all here now: - when headlights are on Zg0 (reverser off, red), they still light up when coupled - when headlights are on Zg1 (reverser forwards or backwards, white), they don't light up when coupled, BUT... - when coupled and headlights are on Zg1, the headlights still emit light to outside, while the textures themselves indicate the headlights being off did it while in a tunnel on KWG, the reverser is turned on and the headlight textures indicate them being off, but the light is still being emitted to the outside. leaving the reverser on while coupled is not a good idea anyways, but while coupling (manually especially) it looks weird, mostly at night. the only solution is to switch the headlights switch to off, but they're always on dimmed anyways (AI trains and whatever services you are playing on, literally all formations are like this) so the Zg0 is still visible. this is a suggestion because I suggest to make it more realistic, I could've also put this in the issues sub-forum but they'd probably just yeet me out faster than I can look
