I have so far spent more time than I should have but less than I'd want with this mod, and so far haven't run into any real issues. I did find a few minor things though:
-The CHP '82 Impala has an amber flashing emissive/polygon/thing and corona instead of the blue one I'm pretty sure should be there. Presumably something that got copied over from an LAPD bar that went under the radar because at a glance it appears fine.
-The '97 airport PD Crown Vic has one unit number on the drivers side, but two on the passenger side. Looks like something funny may have happened when flipping the texture from one side to the other? I still find it interesting just how many different livery variations they've had over the past decades though, but I digress.
-ALS ambulance 3 as it's referred to in the files has its fender lights flash in sync, rather than alternating red/amber like the other ones with a similar setup. That might be intentional, I don't know, but it seemed off to me at least.
And that's it, at least so far. I'm a sucker for old rotator lights so this mod is practically virtual heaven lol.
