NightyLighty
by ItzTK
NightyLighty is a Fabric decoration mod for 1.21.1 that adds a set of toggleable light blocks, remade from the original Night Lights mod.
What it does
The mod adds several light blocks that can be switched on and off, so builders can place lighting that behaves like the Night Lights experience. NightyLighty is a remake of the original Night Lights mod for Fabric 1.21.1, written from scratch by ItzTK after the author found no working Fabric 1.21.1 version of the fairy lights mod they wanted.
Only the Fabric loader is supported, and the build targets Minecraft 1.21.1 only. It runs on the client and the server together, so both sides need it. The code is released under the GNU Lesser General Public License v3.0 only and is open source, with public links to the source code and issue tracker. The latest Fabric file is 0.0.1 for 1.21.1, published on 2025-03-26 on the alpha channel.
