Changing the text on the "European" lightbar

Is there a way to change the text on the display of the lightbar with the LUA console, like with the bus display?
Or is the text some kind of decal?

 

I was messing with game files and i found out that the _g.dds (eur_lightbar_g.dds ; mod_lightbar_g.dds) files of the lightbars contain the text, so its a texture

 

Alright, thank you for explaining this. Now I have to find a way to edit the text without messing other parts up.

 

I think that copying the original files and making a mod will work but i didnt get it i didnt tried so much btw

Obiously i can directly change game files but meeehhh, i prefer to make a new lightbar based on the orginal

 

I don't know remotely enough about modding to do that stuff, and changing the files may not be a good idea. Time to learn the basics of modding...

 

You can always download a mod and modify the mod
