RGB Redstone Lamps (Color Blocks)
RGB Redstone Lamps, published as Color Blocks, adds a colorful version of the redstone lamp whose color follows the strength of the redstone signal it receives.
What it does
Each lamp in the set reads the redstone signal reaching its block and changes color according to that strength. The colors correspond to the signal levels, so a lamp shows the signal it carries without a separate indicator. The lamp is meant for building with redstone, where a player can check a circuit's output by looking at the lamps alone.
The mod is built for Minecraft Java Edition 1.20.4 on the Fabric Loader. It is client and server, so the server and every player need it for the lamps to work as intended. A guide covers how to install and use the mod. The source code and issue tracker are public, and the code is under the MIT License, which makes it open source.
Lamps from this mod can only be collected with a pickaxe that has the Silk Touch enchantment, so a block is kept intact when it is mined. Among the alternatives, Colored Lamps is a Fabric mod for the same version and environment, but under All rights reserved, while Instant Lamp is server-side only and open source under the MIT License, though it targets 1.20.1.
Key features
Signal-strength colors
A lamp changes color to match the redstone signal strength it receives, with each color marking a signal level.
Colorful lamp block
The mod adds a colorful redstone lamp block in several colors, including light blue, as a decorative lighting option.
Silk Touch harvesting
The lamp drops only when mined with a pickaxe that has Silk Touch, so the block is not lost to ordinary breaking.
