Agent's Workshop

After extensive research I have finally found the siren strings for ELS and all but two siren tones are now working in-game!
 
They seem correspond to the OpenIV assigned names but they have the beginning part of the string added. These were all found by me personally through research and experimenting, so you're welcome (also would appreciate this being a pinned topic for others to find). From what I gather the string is basically referring to the location of the siren file in the game's archive ('RESIDENT' being the RESIDENT.rpf and 'VEHICLES' being vehicles.awc, followed by the siren name). Strangely, the siren names identified by OpenIV for the main LSPD tones and the Sheriff Granger tones don't work so I will need help with that. Anyway, enjoy!
 
 
LSPD Main Police Siren:
"VEHICLES_HORNS_SIREN_1" - Police Primary
("RESIDENT_VEHICLES_SIREN_PA20A_WAIL" doesn't work for some reason)
"VEHICLES_HORNS_SIREN_2" - Police Secondary
("RESIDENT_VEHICLES_SIREN_2" doesn't work for some reason)

Firetruck Siren:
"RESIDENT_VEHICLES_SIREN_FIRETRUCK_WAIL_01" - Firetruck Primary
"RESIDENT_VEHICLES_SIREN_FIRETRUCK_QUICK_01" - Firetruck Secondary

Police Bike Siren:
"RESIDENT_VEHICLES_SIREN_WAIL_03" - Police Bike Primary
"RESIDENT_VEHICLES_SIREN_QUICK_03" - Police Bike Secondary

Sheriff (Granger) Siren:
"RESIDENT_VEHICLES_SIREN_WAIL_04" - Sheriff (Granger) Primary
"RESIDENT_VEHICLES_SIREN_QUICK_04" - Sheriff (Granger) Secondary
^ These two aren't working for some reason

FIB Siren:
"RESIDENT_VEHICLES_SIREN_WAIL_02" - FIB Primary
"RESIDENT_VEHICLES_SIREN_QUICK_02" - FIB Secondary

Ambulance Siren:
"RESIDENT_VEHICLES_SIREN_WAIL_01" - Ambulance Primary
"RESIDENT_VEHICLES_SIREN_QUICK_01" - Ambulance Secondary

Siren Warning/Priority Tones:
"VEHICLES_HORNS_POLICE_WARNING" - Police Warning
("RESIDENT_VEHICLES_POLICE_WARNING" doesn't work for some reason)
"VEHICLES_HORNS_AMBULANCE_WARNING" - Ambulance Warning
("RESIDENT_VEHICLES_AMBULANCE_WARNING" doesn't work for some reason)

Siren Horns:
"SIRENS_AIRHORN" - Airhorn
("RESIDENT_VEHICLES_AIRHORN_EQD" doesn't work for some reason)
"VEHICLES_HORNS_FIRETRUCK_WARNING" - Firetruck Horn
("RESIDENT_VEHICLES_FIRE_TRUCK_HORN" doesn't work for some reason)
 
 
My three requests are:
1. Why are a few of them not working, particuarly the Sheriff Granger ones? Could someone with knowledge help?
2. Can we get an AI Sirens mod that makes the AI change siren tones based on the vehicle's VCF siren setup?
3. Is there any way to remove the pitch filters that are applied to some of the sirens? (e.g. the ambulance and fire truck sirens in-game are lower pitched than the actual file itself)
 
 
Cheers everyone.

In real life, there are a few parks that allow this lettering on the uniform. It is rather rare, though. For instance, the “POLICE” lettering was prohibited by a policy on the new design.
 

For all they are this not knowing you can use a Extralight 3 and 4. It work same as the Extralight 1 and 2. Here all ID´s for the Lights:
 
day lights (always on) = 0
left headlight (headlight_l) = 1
right headlight (headlight_r) = 2
left taillight (taillight_l) = 3
right taillight (taillight_r) = 4
front left indicator (indicator_lf) = 5
front right indicator (indicator_rf) = 6
rear left indicator (indicator_lr) = 7
rear right indicator (indicator_rr) = 8
left brakelight (brakelight_l) = 9
right brakelight (brakelight_r) = 10
midle brakelight (brakelight_m) = 11
left reverse light (reversinglight_l) = 12
right reverse light (reversinglight_r) = 13
left fog light (extralight_1) = 14
right fog light (extralight_2) = 15
left rear fog light (extralight_3) = 16
right rear fog light (extralight_4) = 17

You can not use more as 2. I have test it. But you can give the ID to other Lights. But the Problem is this Lights are activated with the extra Lights.
