Amber ENVs?

I’ve been using Custom Visuals’ carcols & vehicles.meta files to get environmental lighting for relevant law enforcement / airport ops vehicles, however it says that it doesn’t support amber ENVs, even though I have my sirensetting changed to it. The amber lights work just fine but I saw that RP groups like DOJ have working amber reflections. How can I accomplish this on my server?

Any help is appreciated.
