J-ELS & NON-ELS — Emergency Lighting System for FiveM

Advanced emergency vehicle lighting, sirens, and signage for FiveM. J-ELS gives you full control over light stages, siren modes, park patterns, takedown lights, and rear matrix message boards — all synced across players with zero XML files.

Non - Els: Resmon (0.01) Driver only
ELS: Resmon (0.02/0.03) Driver only

Performance dose not scale

Realistic Multi-Stage Emergency Lighting

  • Cycle through configurable light stages per vehicle (Q key by default)
  • ELS mode: extras flash using 32-bit binary sequencer patterns at configurable BPM — no siren nodes or XML required
  • Non-ELS mode: stage-based extra toggling for vehicles with traditional siren setups
  • Per-extra spotlight rendering via DrawSpotLight with configurable color, range, intensity, offset, and direction
  • Day/night intensity scaling — spotlights automatically adjust brightness based on in-game time of day
  • Scene Sync: vehicles with scenesync enabled flash their patterns in unison using a shared game clock
  • 30 built-in pattern presets (Alternating, Wig-Wag, Triple Flash, Strobe, Chase, Beacon, and more)

Intelligent Siren Control

  • Three configurable siren modes per vehicle with custom or default GTA audio
  • Hold-to-honk horn with automatic siren restore on release
  • Siren toggle (Left Alt) and hold-to-cycle (R) keybinds
  • Custom audio bank support — loaded server-side .awc siren packs
  • Damaged siren sound when vehicle health drops below a configurable threshold
  • Auto Siren: speed-based automatic mode switching — intersection yelp and pursuit priority with configurable speed thresholds, hysteresis gaps, and debounce timers
  • Per-vehicle siren and horn overrides in config

Automatic Park Patterns

  • Vehicles automatically switch to a park pattern when stopped with lights active
  • ELS vehicles get per-stage park patterns with independent sequencer threads — different flash patterns at each stage while parked
  • Non-ELS vehicles toggle dedicated park extras when parked
  • Park patterns deactivate when the vehicle starts moving again

Takedown and Alley Lights

  • Dedicated takedown toggle (H key) with linked extras and off-extras
  • Takedowns stay on independently of light stages — they persist even when lights are turned off
  • Smart conflict resolution: stage sequencers automatically exclude takedown extras to prevent override flickering
  • Supported on both ELS and non-ELS vehicles

Matrix Message Board

  • Attachable rear LED message board rendered via DUI on 3D props
  • 20-slot prop pool supporting up to 20 simultaneous matrix boards across vehicles
  • Configurable preset messages organized by category (Police, Traffic Control, Pursuit, Safety, etc.)
  • Custom text input with optional server-side restriction to presets only
  • Adjustable font color, flash patterns, scroll speed, font scale, padding, and brightness
  • Per-vehicle position presets saved server-side — attach to any vehicle bone (chassis, bumper, roof, trunk, etc.)
  • In-game position editor with WASD/scroll nudge controls and axis gizmo visualization
  • Toggle board text on/off (K key) without removing the prop
  • Distance-based render optimization with configurable max range and vehicle limits

In-Game Controller HUD

  • Visual status panel showing current light stage, siren mode, takedown, and park pattern state
  • Dynamic button layout — only shows controls relevant to the current vehicle's capabilities
  • Draggable and repositionable — layout saves per-client via KVP storage
  • Configurable scale and screen position
  • Auto-shows when entering an emergency vehicle, auto-hides on exit

Driver Preferences Menu

  • Per-player preference overrides for auto siren, sound effects, park patterns, siren shut-off, keep engine running, scene sync, environment lighting, and controller HUD
  • Preferences persist across sessions via client-side KVP storage
  • Server controls which preferences drivers are allowed to override
  • Accessible via keybind (F5) or /drivermenu command
  • Reset button to restore all settings to server defaults

NUI Sound Effects

  • Custom audio cues for lights on/off, stage upgrade/downgrade, horn press/release, park pattern toggle, and reminders
  • Per-sound volume control in config
  • Optional sync mode: nearby players hear your SFX via state bag replication
  • Driver preference to toggle SFX on or off

Built-In ELS Debug Tool

  • /elsdebug command for building and testing ELS configurations in-game
  • Export configs directly from the debug tool for easy workflow
  • Toggle via DebugMode in config — disable in production

Synced and Networked

  • All state (lights, sirens, horn, takedowns, park patterns, matrix boards) synced to all players via FiveM state bags
  • Entity owner applies extras and audio; all other clients run their own ELS sequencer threads from replicated state
  • State ensured on vehicle entry — late joiners and players entering scope get the correct visual state

Performance Optimized

  • Nearby vehicle limiter: only the closest ELS vehicles render spotlights (configurable cap and max distance)
  • ELS draw thread sleeps at 500ms when no active vehicles are nearby, 0ms (every frame) only when rendering
  • Intensity multiplier cached and refreshed every 5 seconds instead of per-frame
  • Matrix board distance culling with configurable render range and vehicle cap
  • Automatic cleanup of dead, despawned, and out-of-scope vehicles
  • Keep engine running after exit so extras and sirens persist without re-entering

Framework Agnostic

  • Permission gates with replaceable isEnabled() functions — plug in QBCore, ESX, ace perms, or any custom check
  • Depends only on ox_lib — no framework lock-in
  • Lua 5.4 with FXv2 OAL enabled

Easy Configuration

  • Single config.lua controls everything: keybinds, global settings, colors, pattern presets, siren sounds, matrix options, and per-vehicle overrides
  • Add vehicles by model hash with per-vehicle siren sounds, ELS extras, stages, park patterns, and takedowns
  • Matrix position presets saved as JSON server-side per vehicle model

Developer Exports

  • see docs

Quick Setup

  • Drag and drop into your resources folder
  • Pre-configured with example ELS and non-ELS vehicles
  • Includes a custom siren audio pack (dlc_wmsirens) ready to use out of the box
