I have seen other users report very large or bright lights, but I am not sure what causes that as I have not had that happen myself. I would try installing the updated SSLA (link to the Discord is on the LCPDFR page for the mod). Other than that modified graphics settings like visualsettings.dat can cause issues if not done correctly.

I had a similar issue where AI would arrive with no sirens at all in DLS vehicles. I was using Policing Redefined. On another thread (I think on the main mod page for DLS) there was discussion that it does not fully support AI functionality. I was able to confirm that the sirens and lights on my DLS vehicles worked totally fine, but the AI could not turn the sirens on when called in Code 3. It may be a limitation of DLS, but not 100% sure. Other than that explanation I could not figure out a fix.

To my understanding there is some online content available in single player. For instance, you can use a trainer (such as Simple Trainer) to spawn in vehicles that were added into GTA Online updates. Different trainers offer varying levels of functionality and detail so it could depend on that. In terms of "online upgrades" I am not sure what specifically that would be.

I cannot view the imbedded video you have. But, if ELS is working on some vehicles, then ELS is working and it is likely the specific vehicles you are using. Years ago I used to take vehicles out of addon packs to install them in replace slots (e.g., police2) and would have issues since some addon packs use specific config files. Some vehicles worked okay while others were messed up. That can be an issue. Maybe try installing a good/well-known pack and see if the whole pack works, maybe like an addon pack. Also, make sure the vehicles you have don't require SSLA: https://www.lcpdfr.com/downloads/gta5mods/scripts/28560-sirensetting-limit-adjuster/. By the way, it is currently outdated on this website but has been updated by other players on Discord)

First thing I do when installing ELS is disabling the traffic control feature in the els.ini. That does not explain the swerving but it doesn't help as it causes drivers to floor it and crash. My other guess would be the realistic traffic AI mod. In my experience those types of plugins cause more problems than fixes. I have RiskierTrafficStops and Custom Pullover with no serious issues. You could try renaming your mods folder temporarily (which would disable all mods installed in there and make the game revert to the vanilla files) and see what happens with the AI. I second the removal of SuspectSense, I had a lot of issues with that mod and had to remove it a while back.

Sorry for the duplicate post! The website was giving me error code EX0 and was not showing my post as uploaded. NVE seemingly decreased the brightness/visibility of wig-wag headlight and strobe coronas that come from ELS on police vehicles. I have tried modifying various NVE parameters and some ELS parameters without any luck. I have increased headlight/taillight brightness settings in the NVE settings but these do not affect ELS wig/wags or strobes. I can still see the reflections of these lights, but the actual light source is almost removed. It is barely visible up-close. Please see this video for a demo of the issue (https://youtu.be/m-YnAZFZF20). I went on the Discord server for NVE support but the tips I got did not solve the issue. Someone said it could be a carcols file parameter that needs to be edited. I did install the LSPDFR-specific addon that NVE comes with, and NVE was the very first mod I installed in a fresh GTA 5 install. Other players have had this issue (other threads on lcpdfr.com exist but no solutions have been posted to the best of my knowledge). Thanks!!
