Technical Definition
What is VCF (Vehicle Configuration File)?
"An XML file used by the ELS (Emergency Lighting System) to define police light patterns."
ELS Setup
If you are installing a police car with ELS lights, you MUST have a corresponding .xml file in your ELS folder.
The Name Rule
The name of the VCF file must match the spawn name of the vehicle perfectly (e.g., `police3.xml` for a car with spawn name `police3`).
