Many of you have problems with police lights, whether it's the sound or the visual side. In this documentation I will try to explain everything to you in detail.

❓Let's start with an explanation of how sirens work in FiveM and the problem of missing siren sounds.

Why don't standard vehicle models have integrated siren sounds by default? In the case of police models in GTA, such as “police” or “police3,” siren sounds are an integral part of the vehicle's configuration - they are assigned to the model and played in parallel with the engine sound. Regular civilian vehicles, on the other hand, have only the base sounds of the power unit, without additional audio components such as sirens.

Our vehicles have vehicle sounds without sirens as standard.

❓How to solve this problem so that the vehicle has a siren sound?

✅First option:
Renewed SirenSync is a popular tool used in the FiveM community to synchronize siren sounds with in-game vehicles. Its main task is to ensure that siren sounds are properly activated and synchronized for vehicles that don't have such sounds assigned by default, or when those sounds operate in an unstable manner.

✅Second option:
Luxart Vehicle Control is a popular script for FiveM servers that provides advanced vehicle control, allowing players to interact with vehicles in a more realistic and dynamic way. This script is particularly appreciated by the community because it offers a wide range of features that are not available in the standard version of the game.

❗We do not offer assistance in configuring these scripts. You can find documentation on their github or other forums.❗

➡️There is another problem associated with sirens - It is the visual side.

This is a fairly common problem that happens quite often, but the fix is very simple and quick. It is worth noting that the cause lies in the conflicting two SirenIDs, 
and the solution is only to change one of them.
The model has nothing to do here, so it is not a problem related to the vehicle itself.
 

❓How to fix it?

✅ Step one:

Find vehicle files, you need two meta files.
Carvariations.meta and Carcols.meta, these are where you will edit SirensID.

✅ Step Two:

Open Carcols.meta with Visual Studio Code or Notepad. 
Find <sirens> category, then go to <id value="9000"/>

If you found this change the value from 9000 to 9150 for example.

❗ In your case, this value may be different! But the principle is the same, you just change the value.❗

✅ Step Three:

Open Carvariations.meta with Visual Studio Code or Notepad. 

Find <sirenSettings> category and change the value to for example: 9150

❗ The value must be the same in the carvariations.meta and carcols.meta files! ❗

✅ Step Four:

When you have saved the meta files, restart the server. 
Everything should work, otherwise, repeat the steps from the beginning, there is no other solution for this.
