I was just browsing through some google images and found this:

Does anyone think it would ever be possible to get some feature like this in IV?

KevinDV already has one of those on his Ford Fusion

Yes I know that.But its "Police Emergency: Keep Back" in form of a texture.I'm talking about the its usage in real life.Like,they can set the lightbar to reflect a set of predefined texts,whenever they wish to.

Not that I'm aware of. I'm afraid that could be the best you'll find.

Prehaps in GTA V, we'll just have to wait and see

It would be possible if someone made a light mod that can toggle textures, and even then, car modders would have to adapt their vehicles to the mod.

I hope Caine will think about it upon his return.

The maximum amount of text you can get on a display like that using ELS is 3 different texts, seeing there are only 3 availible secondary light extras, I do not think that Lt.Caine will even bother about doing that as it is currently possible to do it with ELS, the only thing that you cannot do is to make the text along the bar slide across.

My Fusion's lightbar only supports 2 with the last release I made, what I can do is adapt a special emerglights file just for the matrix display, then you can edit them as you wish, however you could just modify the emerglights file I made for the Fusion, that way you can also use your own customized texts in it.

I can see this being possible using the in-game scrolling signs, then you would be only limited by the size of the sign, I just can't find them in the game's files for reference.

@Kevin: +1 to Sniper.Have you noticed that sometimes there are Audis (Auditoriums) @ Star Junction have sliding text through them.Is there any way,we can get it in a micro form for car lightbars? I don't really know what technology R* has used to do that,but if its possible there,I'm sure there must be a workaround to get it in cars,as well.
