# Sirens

If an emergency vehicle spawns but the sirens or emergency lights do not behave correctly:

## Check the vehicle type

Confirm whether the product is designed for your server's emergency-lighting setup.

## Check extras

Some lighting components may be controlled through vehicle extras.

## Check your emergency-lighting system

Different FiveM servers use different emergency-lighting systems. Your server may use a custom system or another vehicle-lighting resource.

## Check for conflicts

Temporarily test for conflicts with other emergency vehicle scripts.

## Contact support

Provide:

* Vehicle name
* Video of the issue
* Emergency-lighting system
* Framework
* Relevant scripts
* Console errors

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://modster-customs.gitbook.io/modster-customs-docs/emergency-vehicles/11-sirens.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
