Dynamic Sirens & Emergency Lights

Dynamic Sirens & Emergency Lights is a powerful and modular siren system designed to bring realistic emergency lighting to your Unity projects. Whether you need fully customizable sirens or performance-optimized shader effects, this asset provides all the tools to create dynamic police, emergency, or industrial sirens with ease.

Modular & Customizable Sirens
- Works with both single-model sirens and modular sirens where you can mix and match different siren parts and light modules.
- Toggle individual front lights, side lights, and the siren itself for complete control over how your sirens behave.
- Supports two siren variants: Code-Based Sirens – Full customization over light behavior and patterns. Shader-Based Sirens – Optimized for performance with Off, Steady, Strobe, and Two-Way Strobe modes.

Dynamic Light Patterns
Customize how your lights behave with multiple preset styles:
- All – All lights flash together.
- Sides – Alternates effects between left and right sections.
- Sequential – Lights activate one by one in sequence.
- Sequential Fill – Sequential activation but keeps lights on until all are illuminated before resetting.

Fine-tune light behavior with:
- Steps, Step Duration, and Step Cooldown – Define how many flashes occur, how fast they happen, and cooldown time before repeating.
- Custom Color Selection – Set up a list of colors to iterate through.
- Per-Light Color Switching – Each light cycle selects the next color in the list.
- Random Color Selection – Randomizes colors instead of following a sequence.
- Reverse Mode – Flips the flow direction for Sequential and Sequential Fill effects.

Realistic Beacons
- Fully customizable rotating beacon lights.
- Adjust color, rotation speed, and glass transparency for authentic lighting effects.

Interactive & Real-Time Features
- SirenMic – Uses the device’s microphone to simulate a radio-like siren effect, perfect for voice commands.
- Input Support – Toggle sirens using keyboard controls for interactive gameplay.
- SyncLights – Ensures nearby sirens synchronize their effects to create a cohesive and epilepsy-safe lighting display.

Siren Audio
- Play a siren when holding a button or on toggle, easily add or change the siren clips.
- 7 different audio clips are included to get you started.

Optimized Performance & Seamless Integration
- Code-Based Sirens for full control over effects.
- Shader-Based Sirens for high performance with minimal CPU/GPU usage.
- Compatible with any Unity project – easily integrates into your existing systems.
