Ok my first lesson

To change the lighting in interior you use first:
content>cars>honda_integra_dc5_typer>data = lights.ini
And in the content manager you have to find the file name by clicking once for example .... on the clocks.
Then you look for the right name in lights.ini
[LIGHT_9]
NAME=speedo_SUB0
COLOR=10,0,0
Values are shown COLOR=RED,GREEN,BLUE
But if your car uses csp, then you need to look for the appropriate section in the
extensions folder:
content>cars>honda_integra_dc5_typer>extension = ext_config.ini
There you have to read and look for a suitable description .... Simple right
