Let's say this...
[ POLICE4 ]
Status = on
File = mnvn_vector
...is one of your entries.
Copy + Paste + Rename POLICE4 -> the vehicle you want ELS-enabled (in this case, POLICE4 -> POLICEW)
[ POLICEW ]
Status = on
File = mnvn_vector
Now, if you want a different lighting pattern, you would have to create a new config file. It's the other .ini files in the folder.
So in this case, you can duplicate the mnvn_vector and just rename it to something. We'll call it "spreilly_config"
So now we have this:
[ POLICEW ]
Status = on
File = spreilly_config
If you want to actually change the patterns, you'd have to open your newly-created "spreilly_config.ini" file and edit the following:
^ This, going down the list, switches the vehicle to slicktop mode (less reflections), changes the lighting stage activation type, and enables the arrowboard to be hooked up to the trunk/hood.
^ This edits the settings for steady-burns you can toggle and, going down the list, cruise-enables AI cars, disables cruise mode at the 3rd stage, and determines what of the four main lights it uses.
^ This changes the sound settings. Determines what horn to use for the vehicle, and whether certain siren tones are enabled/disabled.
^ This enables/disables GTA vehicle light-based wig-wags and strobes and determines what pattern.
^ This changes the type of flashing that the warning lights will do (strobe, halogen, etc.), determines the pattern if desired and edits certain aspects of the way these lights will flash.
^ This changes the type of flashing that the primary lights will do (strobe, halogen, led, etc.), determines the pattern if desired and edits certain aspects of the way these lights will flash.
^ This changes the type of flashing that the secondary lights will do (strobe, halogen, led, etc.), determines the pattern if desired and edits certain aspects of the way these lights will flash.
^ This changes the color of the environmental reflections of the lights.
