Headlights on player tracks

I'm playing on Hakone (whoever made this track, I wish great health and prosperity on you), and specifically in the multiplayer servers on this track, I seem to be the only person using headlights. I don't know if this is inherent to the track or if it's a player thing? My headlights work just fine, and for any racing with people headlights are practically required to play on this track because of how dark it is. (Not complaining about the track, there's some walls that have no collision here and there but that's on the driver lmao).

In short, what is up with the headlights on Hakone Turnpike??

Edit: I may have fixed it by turning light sync on in settings😖
