https://www.beamng.com/resources/realistic-headlights.25808/ (This is the repo version) Try this out, there's a forum version and a repo version.
It's a mystery as to why the BeamNG devs won't fix something so simple. I made my own mod that changes the headlights and now night driving is fun and realistic.
the devs generally dont do small fixes to this sort of things, when they do they basically overhaul how lights works so they are even more realistic than currently, i imagine thats what they will or are doing
they want to add them realistically of they ever do, this means it's imposible since the simulation internally runs at 4000hz which iirc is like one simulation step per like 0.05 seconds and airbags deploy faster than that so it quite literally can't be simulated realistically
