okey, will do that

Yes, i installed both of those.

I attempted to download this pack: https://www.lcpdfr.com/files/file/20065-los-santos-police-pack-tpd/ earlier today. I followed the instructions closesly but something possibly went wrong. The police vehicles does spawn in and drive normally, but their lights do not work. is there any quick fixes for this, or did i install wrong?
