I've recently published a D&R Magnum siren mod for the sheriff grangers and I noticed that are not a lot of siren mods for GTA 5 compared to GTA 4 siren mods. However considering that I've been making a couple of siren mods to fill the void, I plan on using LSPDFR in a few months after getting GTA 5 via steam for the PC. 

Out of all the siren mods for GTA 5, what are some of your favourites to play with and to use for any emergency vehicles in game? =3

Well that's because GTA IV has been out for 7 years now and GTA V is barely a year old on PC.

I've personally always liked the Touchmaster Delta so I run it in both IV and V.

The Federal Signal Touchmaster Delta siren is pretty cool. =3

My favourite sirens are the Code 3 Mastercom B, D&R Intimidator, Whelen Cencom, old school Federal Signal sirens, and the Federal Signal SS2000.
