Emergency Vehicle Creator

Emergency Vehicle Creator is a Roblox Studio plugin for building emergency vehicles without writing their lighting system by hand. It includes editors for flashers, rotators, faders, sirens, equipment, and light groups, then generates the scripts and settings used by the finished vehicle.

I took early inspiration from Dawnstar’s Siren Tool for FiveM. The hard part was not copying it, it was creating something that worked for Roblox creators and expanding it to more then just emergency lights. I wanted to make a tool that would let a creator build a working system without writing code, but also let an experienced creator tune every part of it.

Features

• Visual editors for flashers, rotators, faders, sirens, equipment, and light groups
• Pattern timing and in-Studio previews without hand-written vehicle code
• Generated settings and runtime scripts for the finished vehicle
• Reusable configurations for applying a setup across a vehicle

Building the editor

Emergency lights are time-based, so a static properties panel is not enough. The plugin lets a creator group lights, lay out patterns, change timing, and preview the result. A beginner can build a working pattern, while an experienced creator can make a highly customized lighting system.

Version 3 rewrote much of that flow. I reduced the number of steps, made editing states clearer, and made it easier to reuse a setup across a vehicle. The Studio plugin and the vehicle runtime remain separate: one creates the system, and the other runs it in game.

Release and support

I publish the plugin on the Roblox Marketplace and as versioned GitHub releases. The repository also holds the development place, build tools, user guide, and developer documentation. Maintaining the plugin has been a long-term project, and I continue to add features, fix bugs, and support creators who use it.
