Description
An advanced emergency-lighting controller for ESX/QBCore/QBox service vehicles: one key cycles through off, warning, secondary and primary stages, toggling sirens (muted at lower stages) and indicator/lighting patterns. Each change is broadcast through the server so every nearby player sees the same lights. Servers sell it because emergency-services communities treat synced, multi-stage ELS as a must-have.

Known Failure Modes & Corrective Prompt
- Local-only lights, applying the stage on one client leaves others dark; broadcast through the server.
- Raw handle over the wire, entity handles are client-local; serialize with
VehToNet/NetToVeh. - Unvalidated stage, a malformed stage value spams sirens; clamp/validate it server-side before re-broadcast.
Corrective re-prompt: "Send VehToNet(veh) and an integer stage to the server, validate the stage is in 0..3 and the netId is a number, then TriggerClientEvent('els:update', -1, ...) to all clients which resolve the vehicle with NetToVeh before applying, never apply the stage only locally."
Framework Integration
ESX: getSharedObject() is only used for job-gating which players may toggle (e.g. police/ems).
QBCore: gate the toggle on Player.PlayerData.job.type == 'leo' (or ems) before accepting els:sync.
QBox: same job gate via exports.qbx_core:GetPlayer(source); the netId sync path is framework-agnostic.
Profit Potential
$400-$6000/mo on Tebex (expected ~$1500), derived from the $50-389 paid-script band against a corpus of comparable Tebex sellers (median ~$11.85K/mo), scaled for a hot emergency-services niche.
Trend Signal
🔥 hot, strategy: Niche-matrix: emergency-services servers are a large active pre-launch segment; advanced ELS patterns are a top paid ask, hot.
Sales Angle
Position as the synced, multi-stage ELS that separates a serious emergency-services server from a cosmetic light bar. Recommended Tebex price: $389.
