I have installed a mod called something along the lines of ELS from the lspdfr website( I followed Albo1125's guide.) I downloaded the newly updated one and I am having problems with sirens with all of the police cars I add in the game. I added a BMW British version and when i activate the siren and lights (or just lights) I only get the siren coming through and the brake lights flashing and nothing else. But when I call for backup by pressing B and request local response units the API spawns in with BMW's which is a replica of mine and they have flashing lights and sirens on theirs. If I steal one, I am not able to turn the engine off nor am I able to turn the siren or lights off. If anyone could suggest any help that would get great.
If anyone would like to see this problem I don't have any problems showing on skype/discord/teamview.
[I don't know if this is related hence why it is at the bottom, but I have problems replacing all other types of police car other than "POLICE" I am using OpenIV too, so I don't know what the problem is.
