Changes to the carvariations.meta is necessary for the proper paint schemes to spawn in traffic and for the headlights to appear correctly at night.

If you have already altered your carvariations.meta in mods\update\x64\dlcpacks\mpchristmas2\dlc.rpf\common\data, copy these lines below and replace the entire Vigero entry in carvariations.meta:
