The 406's headlights still don't really work, I don't know if someone's posted this already but I literally can't drive at night with the hud off, and can barely drive at night with the hud on. I haven't checked with the 403 yet but the 406's still broken.
I had the same problem driving the 403 on HMA on the PS4 yesterday evening. Did a service that started at 0:40. Set the headlights to full high beam, but it didn't realy light anything up. No problem while LZB is active, but I was kinda nervous that I would get a swanstbremsung on pzb because you can hardly see trackside speed restriction signs.
