Frequently asked
Does Variable Copper Bulb Signal work on Minecraft 26.1.2?
Yes. 26.1.2 is the newest Minecraft version Variable Copper Bulb Signal declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.
Which Minecraft versions does Variable Copper Bulb Signal support?
Everything the author has declared, from 1.21 up to 26.1.2. The full list is in the table above, with the Java runtime each version needs next to it.
Do I need to install Variable Copper Bulb Signal on the client or the server?
The server only. Players join with an ordinary Minecraft client and install nothing.
Which loader does Variable Copper Bulb Signal need?
Fabric, NeoForge, Quilt, Forge. A build for one loader will not load on another, so this is the first thing to check before the Minecraft version.
Which Java version do I need for Variable Copper Bulb Signal?
Java 25 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the mod itself.
What licence is Variable Copper Bulb Signal under?
MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.
How do I install Variable Copper Bulb Signal?
Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.
