Alarm Mod
by Romanfoks
Alarm Mod adds an RGB siren block, lit by the Veil rendering library, that signals hazards in factories and technical builds.
What it does
The siren is a working electrical device for Create, wired into a Power Grid network. Four connection points sit on the mounting face: one each for red, green and blue, plus a common ground. Colour comes out of how the wire is connected, a channel resistor sets the brightness, and a channel level follows the voltage across a rheostat. The siren mounts on a face and aims its light away from that surface.
Its light is rendered with Veil, which draws an ambient glow plus two sweeping coloured light cones. Lapis, milled dust and redstone are reduced into a Redstone Acid and combined with iron to produce a Redstone Charged Iron, and nine of those craft the block. Create, Create: Power Grid and Veil are required, and Sable is an optional dependency. The mod is for NeoForge 1.21.1, runs on client and server, and is open source under the MIT License.

Use cases
Factory hazard signalling
A siren on a production line can show a colour for each alarm state, driven by Create machinery.
Base defence
Sirens placed around a technical base give visual warnings when a sensor or circuit trips.
Who it’s for: Players building Create factories or technical bases on NeoForge 1.21.1 who want visible hazard signalling. Server owners need it installed alongside the players' clients.
How it compares
NoxLights is open source under the MIT License, runs on client and server, and is built for NeoForge 1.21.1, so it covers similar lighting ground. Sirencraft targets Forge and NeoForge across 1.20.1 – 1.21.1 and is licensed as All rights reserved, so its source is not open. Immersive Flashlights is NeoForge 1.21.1 only, under the MIT License, and runs on client and server.
