Hey,
So I already googled it and lead it back to this site, it appears someone had the same issue. But mine is different maybe?
My issue is, even when I put the vehicle pack (in mods folder) as well the ELS xml file into the ELS folder it turns out that after running LSPDFR, the ELS vehicle light bars are far too dim. Default vehicle are flashing fine, however there ELS is not responding correctly.
Yes I did put these in the mods folder from the beginning. I followed the guide perciously.
Any ideas, thanks!
