Cool, no probs
I edited my previous post, what happens when you Export to META/XML (.xml)?

@Twingo69
Opening it with OpenIV yeah?
If it won't open in OpenIV, try right-clicking 'carcols.ymt' > 'Export to META/XML (.xml)' > export to a location & try opening & editing with a text editor (Notepad++ etc) & see what happens? Drag & drop to reinstall the edited file (no need to change the file extension).

To change the global xenon colour open up the 'carcols.ymt' here:

...\mods\update\update.rpf\x64\data\carcols.ymt

Scroll to the bottom of the file & find these values & change them to what I have here:

  <GlobalVariationData>
    <xenonLightColor value="0xFFFF2D2D"/>  <!-- 'Hex(FF2D2D)' Red -->
    <xenonCoronaColor value="0xFFFF2D2D"/> <!-- 'Hex(FF2D2D)' Red -->
    <xenonLightIntensityModifier value="1.50000000"/>
    <xenonCoronaIntensityModifier value="1.50000000"/>
  </GlobalVariationData>

It will use this colour of red.
You can use that site to find the hex values for colours. Just enter the last 6 digits of the GTA V hex hash ('0xFFFF2D2D' for example, becomes 'Hex(FF2D2D)') on that site).
Using that process you can go from colours to hex hashes or vice versa, say you want to test different shades of red out or try a different colour etc

@Twingo69
You can change the colour of the headlights for individual vehicles easily enough doing it manually, you just won't be able to change the colour ingame.
You can also change the global xenon colour manually if you are happy with all vehicles having the same colour xenons?
Let me know what functionality you want & I'll show you the best way to get it done, if it's possible

@Twingo69
Simple Trainer was updated 3 days ago, so is up-to-date.
It used to work (perhaps a GTA V update broke it).

Your best bet is to contact a few Trainer mod authors & see what they know about it/have any plans to implement new functionality for it etc.

@Twingo69
I think you would have to use a trainer with that functionality, try Simple Trainer & see what headlight colour options it offers.

@nussmann

In the 'carvariations.meta' edit this:

      <sirenSettings value="1" />

to this:

      <sirenSettings value="0" />

& see if that gets rid of the flashing lights

@OsPopo
In 'handling.meta', lower the 'z' value for '<vecCentreOfMassOffset' (can be negative if required)

      <vecCentreOfMassOffset x="0.000000" y="0.000000" z="lower this value" />

Lower it in steps of ~0.5 until it stops tipping over & then edit in smaller increments (up or down) until you find a nice value for it.
Generally, somewhere just below the point where it stops tipping over is usually best. A bit too low & the vehicle will hug the ground unrealistically & lack any roll. Much too low & the the vehicle will tip over into the corner rather than to the outside/lift up at the back on acceleration/wheelie on braking etc.

@bogdanvor
I haven't used the AddBlips mod, but perhaps try making sure 'minimap.ytd' is 100% vanilla & no other mod has replaced/edited it. Other than that, I'm not sure.

@Thighmangler
A lot of useful 'dlclist.xml' info in this tut

Alternatively, either use a codeblock to post your 'dlclist.xml' here (see below) or upload your 'dlclist.xml' to somewhere like MediaFire or PasteBin, so I can download/take a look.

Codeblock:

```xml
Copy these three lines to a blank txt file, overwrite only this line, copy all & post into gta5-mods forum post.
```

Detailed codeblock instructions:

• copy the three lines above into a '.txt' file (any empty one will do)
• then open 'dlclist.xml', press Ctrl+A (to select everything in there) & then Ctrl+C (to copy everything)
• Back to your open '.txt' file, highlight all the words on the middle line & then hit Ctrl+P (to paste you dlclist data & replace the words on the middle line)
• Then hit Ctrl+A again (to select everything in there) & then Ctrl+C again (to copy everything)
• Back here on gta5-mods, use Ctrl+P to paste the data into a reply/post

DLC Limit:
If you remove a few other dlc's from your 'dlclist.xml' & the map/s start loading, that would suggest you've hit your dlc limit. To fix, you would want to combine add-ons together into add-on car packs to reduce the overall number of dlc's.
That, or perhaps a different 'gameconfig.xml' might give you a higher number of dlc slots to utilize.

Also, if you're still having issues, link to the map mods you are talking about
