What it does

The mod introduces three additional items used as aviation obstruction lights, alongside a flickering effect redstone torch. Each item produces its own lighting effect, so builders can pick a light that matches a tall structure or a city skyline.

The author notes that the mod was tested in large cities such as Tokyo and Osaka, where rendering the entire area slowed performance, and that it runs without issues when limited to specific districts like Shinjuku or Umeda. Smaller cities such as Nagoya showed no major issues. Screenshots for testing were taken with Voxy Bliss, and the code was written with Claude Code.

Installation needs Fabric API. AviationLights runs on client and server, so both the server and every player need it. It is released under the MIT License and is not open source. Files target 1.21.10 and 1.21.11, with 0.1.0 for 1.21.11 as the latest beta release.
