Yes, this can be configured in: lspdfr/data/agency.xml
If you have Ultimate Backup you may also want to go to: Plugins/LSPDFR/UltimateBackup/DefaultRegions.xml

Delete GTA5.exe and re-verify files and try running Rage Plugin Hook again.

No problem 👍

You are on 1.95, and the latest is 1.96. Follow this again: https://i.darkvypr.com/update-rph.mp4
 
The reason you are on 1.95 is user error.

This massive red things may be worthy of your attention. 😄

No. However, Non-ELS vehicles can arrive with lights and no sirens on which is configurable in the ultimate backup ini file. But if you have ELS cars installed, then they will always arrive code 3 with sirens if code 3 is set. you can change els vehicles to show up with no lights and no sirens as well. But no code 3 just lights option since the coding for that hasn't been configured yet.  Although, I believe rich's police enhancements has the option for all backup to show up code 2 with no sirens and lights until they reach your proximity. If you have your lights on, when they reach a certain distance from you, theirs activate too. But with sirens as well if the backup vehicle is ELS.  Maybe you can give that a try? Or use Non-Els vehicles in vanilla slots and run addons for you to get what you are asking for.  

Not the same thing.   Looking for different responses for different scenarios.  So far everything is a compromise. 
 Ideally, looking to be able to do all of these 
A) Traffic stop backup, arrives silent, but puts on lights when arrives (UB does this now)
B) Code 3 backup arrives L+S regardless of current stage of player lights (UB does this now)
C) Silent backup, arrives no lights or siren. (RPE can do this, but then A+B above don't work properly)
D) Player on scene with light on.  Calls code 2 backup, Arrives No lights or siren but puts lights on upon arrival (UB can do this)
 
Not really complaining, just wishful thinking.  Never hurts to ask.
