I would remove Assorted Callouts because I don't think that is fully compatible with 4.0.  Also go into Traffic Policer's ini and disable all the ambient events because those are causing problems like that.  Most of those ambient events are in either super callouts and event callouts anyways.  Traffic Policer is still usable and I think it might still be required if you and Stop the Ped but disable the events. 

Yeah, some of us forget to mention that you do need to pass the first couple or few missions of GTA Story Mode before LSPDFR will work.  Just a little tip, when you first start in the missions, your character will be Franklin, at that point Trevor or Micheal are not open yet.  If you play in story mode  long enough to open Trevor and you save the game with your last character saved being Trevor, that is what LSPDFR is going to see you as...kind of.  Trevor has a problem with the Lost MC's.  Whenever you drive by the Lost Garage in Mirror Park or through Stab City the Lost will automatically open fire on Trevor.  When you play LSPDFR it somehow needs to link your last saved character and if your last saved character is Trevor then when you are on duty and drive by the Lost Garage of Stab City the Lost will open fire on you as an LEO.  If you want that to happen then leave it.  If not then in the story mode switch to Franklin or Micheal.  I find Micheal being the safest character.  You might have some trouble in Ballas territory where sometimes they open fire on Franklin and they will do the same in LSPDFR if your saved character was Franklin.  If you want gangs opening fire on you as an LEO in LSPDFR then choose Trevor or Franklin.  If not then go with Micheal.  That is what I noticed about 3-4 years ago.  I doubt anything has changed so what I just explained might still be true.   

You need to copy the Update2.rpf into your mods>update folder.  Replace it.  I need to remember that also.  I had to do that last time to solve the infinite loading screen.  

After install EUP Law & Order and if you want the EUP Serve and Rescue, most players have that clothing glitch.  That glitch is corrected by one of the 2 file link above.  Just install the Basic Configurations.  Install it and go in game to make sure the uniforms look good.  After that then you could install your custom clothes packs.  I never installed a custom clothes pack so I don't know what happens.  I just used whatever EUP has.  If you wanted to make changes I think you can go to your main game folder, then lspdfr folder, then data folder and open the cop_preset_outfits.  That is where the ai officers clothing would be.  Once you install that Configurations files above, it puts files in the custom folder that is in that same folder you're in.  In the custom folder, you find the agency you want to edit and open that file like.  It can get confusing if you are not familiar with how the wording in the files are.  Since you are using EUP you'll want to edit the custom folder.  You can add/remove vest, earpieces like you mentioned but the trick is trying to find the number and the body area it would be.  I would have to go in game and open EUP, customize the uniform and save it.  Then I can go to the file where it is saved and copy it to the proper agency in the custom folder.  Anyway that is a real detailed description of how to custom your EUP uniforms for yourself or for your backup officers for anyone who wants to.  If you found a uniform you like that you downloaded then that would be easier but I've never done that.  

That could manually be fixed but it would take time to find the right Upper Skin in EUP and have to do that with all the uniforms you are having a problem with.  Download and install this should fix it.
 
 

Could be a few problems.  If the vehicle you pulled over all of a sudden goes straight in whatever then you probably have ELS and you need to open the ELS ini in your Main GTAV folder and change ElsTrafCtrlOn = false
Yours is probably defaulted to true so change it to false like I have above.
Traffic behind you would stay behind you in a traffic stop but sometimes they are anxious and go around you.  Especially where you are on a narrow road. 
If the car doesn't pullover in a good spot then you can use Custom Pullover and instruct the driver where to pull over.  That's a nice mod here.
 
 
If these don't work then you could make a vid we'll see what's wrong.  Your English is fine.  I see more grammar errors and misspellings from people who do speak English who don't proof read before posting.  I am at fault with that at times LOL.  😀

Did you try this?

Should get rid of Traffic Policer because it is very outdated and might be causing the problem somehow.  BetterEMS requires RAGE NativeUI and the one included in BetterEMS is outdated so you might update that.  As of now, it was updated 2 days ago.  Maybe that is the problem.

That's not a common problem so I'm not sure.  Are you using lspdfr's backup or Ultimate Backup?  Either way it would be the same key (B) and then you select what Code and Agency. 

I occasionally had that problem and I read somewhere that just a restart of your computer should fix it.  I would restart the computer and then load the game and the lights worked again.  Hopefully that will work for you.
