Hello! Idk it's just in my country or not but in my country the headlights' lights of almost every vehicles is yellow/cream but the headlights' lights in the game is completely white. I think adding yellow/cream headlights would be good. (and more realistic)
Led and xenon headlights are a cool blue white and halogen lights are a soft yellow white. We have both of these in game and it represents 99% of the cars on the road across the world.
Oops! I didn't try turning on the headlights of a new car like etk 800 and an old car like blue buck at a time and next to each other (I just tried turning on them in separate places so I thought every headlights are white) and when I did it, I figured out there is a difference between light color of them. Sorry I was wrong, you're right
