Hey, try to share your idea with Bryan in this thread: Released - Realistic Headlight Patterns | Page 8 | BeamNG
I mean... that is actually a really good point. Definitely with the classics. Do modern cars still do this (you know... with the LED lights and what not)? I genuinely have no idea. I know that if they were wired like classic cars they wouldn't as their isn't enough electrical load on the system to cause it to happen, but maybe it has been programed in?
