Changing ELS light colors

How would one go about changing light colors on a els vehicle? I tweaked the xml a little but it just seeming to break the lights. Trying to change this beauty to red/blues instead of just blues

You need to change the textures in the .ytd to red/blue not just the XML

There is only one light texture, it seems to be the lights on the car not the lightbar. In the xml file I changed around some of the lines from blue to red but now they seem to be flashing blue and purple. Almost like the red is trying to come through but cant lol

That’s GTAV’S natural shader stuff. Red and blue lights making purple.
