I am unsure. There may be engine packs that contain stuff for this. I don't really play with any other mods other than this.
Yeah, BeamNG doesn't really have the best headlight system currently. Never has, really. Hoping they fix it in an update. Till then, just gotta work with what we got LOL
Please make the Whelen edge 9000 have selectable lens. Some Whelen lightbars have complete blue or other colors like that rather than the amber lens on the back.
You might be able to look into the realistic headlights mod that's made by PostmortemSlayer and is being continued by someone else right now, I'll leave a link. https://www.beamng.com/threads/realistic-headlight-patterns.84947/
Toyed with merging the realistic headlights by jfef and PostMortemSlayer mod with the Crown Vic. Here's the result. Unpack the zip and drop the modified jbeam file in "\vehicles\crownvic\jbeam" (Remove quotes). Note that you will need the other mod too because it uses the textures meant for the second gen Pessima. (Let me know if this kind of merge is wrong to make public and I'll take it down. First try at modding Beam in this way. I usually don't touch .jbeam files)
Do you plan on branching out to maybe Pierce Arrow XT fire trucks or even SWAT/HRT vehicles like the Lenco Bearcat?
Don't just tell people to do stuff for you because you want it. You ask nicely in the form of a request or suggestion. Also, you only do it once, not twice within 24 hours. The world does not revolve around you, and you won't always get what you want. Also, the Crown Victoria wouldn't be eligible for the Gambler 500 event, as it is a real vehicle that would require a license to be officially featured in the game, as well as many parts that are under the name of real brands that go along with the vehicle. If I remember correctly, entries must be repository-friendly to be eligible for the Gambler event.
