Do u use mods folder? I would recommend u to use manual installation if you already have moded game in future. Unless u really know it will not conflict with ur moded game. U can always open .oiv packages via Total Commander to see what is inside. 
This is my solution btw :P

1) Yes, by all means backup your plugins folder and any other script mods. That will save you some time.
2) NaturalVision is quite hefty in terms of it's requirements and install. You'll need to install VisualV and then NaturalVision. But as long as you use the OpenIV mods folder you should have a reasonably easy install. Always use the mods folder, so as to not overwrite game files fully.
As for radianceV I don't use it so can't say if it's worth using or not.

Then redux is probably the problem. Something somewhere will still be modded and that's what is causing issues.
I think a full clear out of your folder will be the best bet, even if it is a paint to redownload a 60GB game. Unless of course anybody else has better ideas.

I use NaturalVision which requires VisualV (so ENB series and ReShade)
This screenshot shows the file I remove, allowing me to play online no problem at all. If removing just dinput8.dll no longer works for you try checking for the other dll file d3d11.dll and remove that. If this still doesn't work my recommendation would be to uninstall GTA V, delete all remaining files then reinstall GTA V. This will give you a fresh clean folder to re-add your mods to.
 
Also you state you used GTA Redux, be sure you only ever use a mods folder for this (through OpenIV). Altering the game's own files will always cause problems if you ever forget what you changed etc.

Can you send the RGH log?

Yes.

If you put any vehicle in a police slot then it will have siren, and usually flashing brake lights (I don't know if this is the case for police bikes - the flashing brake lights).

Download pain.net it's alot better than normal paint. It's really not that hard. Takes 5 minues to learn everything in paint. 

If you want it to be just like in the images you showed, then you could just use a regular bike in the policeb slot (unless it doesn't have sirens) and then have someone replace a weapon that can be used while on a vehicle with that sign.
An "unmarked" bike with hidden lights would also be possible - something that exists rarely in the United States.

You could use this, Just export the texture using OpenIV and edit it in paint (remove logos, or just put a completely different colour over the top). 
 
 

i got it fixed some reason it didnt update when i replaced the files to the more updated version

That's because you installed Zippo raid Injured system that comes with his blood and volience overhaul. Refil your armor bar with a trainer or get in cover until your armor bar refills or delete the scripts in your scripts folder.

CalloutsV
 
 

For me, I removed Secondary Callouts from the plugins LSPDFR folder and I have had no backup issues since.
Fisky111 is currently updating this Callout package, and we should all be good to go after he does.

Well,I feel you and I totally agree with your thoughts on a nice police themed game! I don't know about a map mod but I can advice you to look for a complete save game (I don't know if someone can share it,though) . Anyway,we can discuss this on PM,to avoid getting off topic. Ok :)?

heck to be honest i just downloaded gta last week so im all new to this mod stuff but once i saw a video of the lspdfr part i was like yep i got to download that ha , they need to make a real game like this ,  i think they would make good money with a law enforcement edition like this ,  but  now i have to figure out how you do the vehicle mods ,  i know this is off topic but do any of you know how to get access to the full map without actally beating the game ?  I only downloaded gta just for the lspd plugin but since i havent played any of the missions i cant get access to the airport and half the map is still shaded out ?

Thanks to you! I would have never figured it out on my own! Thanks :)

yeah he told me he took it down and is working on fixing it ,  glad it worked out for you also kenobi

yeah the only plugins i have are code 3 callouts . calloutv , police radio , arrest manager, traffic policer,  and arrest warrant callouts ,  as for the plugins i have ragetrainer v , breathalizer , vehicle search , ,  and passive radar , 
 
I removed secondary callouts because everything was working till i added that then once i removed it just the dll and ini it started working again, i still have the audio files but that didnt seem to change anything by keeping them

Secondary Callouts just recently updated and claims he fixed that bug. Hope that helps brother

all i know is i had the same problem with a patrol car just sitting in the middle of the road anytime i called for backup when in a pursuit and i took out the secondary callout dll and ini and now my backup works again
 

Hey guys take out your secondary callout dll and the ini file and it works again ,  so it must be something with the secondary callouts ? I hate to take those out since they are some of my favorites

Alot of people are having this problem, myself included

I'd recommend giving Keep Calm a try.

Sounds like CalloutsV the successor
