The title is self-explanatory, but in case you don't know accent interior lighting is basically just lights hidden in cheeky spots in a car's interior, particularly under the dash. I know this is kinda stupid and not everybody likes it but it could bring more interior personalization. Also just to be clear I'm not asking for the obnoxious type like this: (WAY too bright and flashy) But something subtle like this: (Not too flashy or bright, but noticeable) *Again, I don't expect everyone to like this idea as it isn't everyone's cup of tea. *These lights would need shadows of some sort to prevent the light from showing outside the car and I don't think that's as simple as it sounds. It could be customizable by the color palette or just selections in the vehicle configuration menu (i.e. "Red Interior Accent Lighting"). I'm sure that interior customization is not the devs' priority right now and it may not be for a while, but it would be cool to have eventually.
