Summary
This mod turns a Moonside LED lamp into a Claude Code color status indicator.
Navy means it’s working, sunset mango means it’s idle, and purple means it needs user input.
Works via macOS BLE and is best used with Moonside Halo specifically.
One thing I’ve learned from using Claude Code is that, sometimes, you just have to let Claude cook. Ideally, Claude will generate a ton of code in a heartbeat, but sometimes it needs to chew the cud for a little longer, which usually means it’s time to stand up and grab a mug of coffee. But what if you wanted to know what Claude is up to without being tied to the monitor?
Enter this mod for an LED lamp that turns it into a Claude Code status indicator. Now you don’t have to sit around and wait for Claude to finish; just a quick peek over at your desk, and you’ll know what’s up at any given time.

This one hurts to write.
This open-source mod turns the Moonside LED lamp into a Claude Code indicator
With a few caveats
This cool little project comes to us via MoutainSnow [sic], who took to the Claude Code subreddit to show it off. They say they’ve seen other people turn their Moonside LED lamps into Claude Code color-coded status indicators in the past, and wanted to give it a shot themselves. From the looks of the video, I’d say they did an excellent job.
The code was created by bobek-balinek over on GitHub, who has a full project page for the “Claude Lamp.” There, you can check out the setup guide, see all the code, and get this cool lamp working in your own home, just like how MoutainSnow did.
Here’s what each color means:
State
Lamp
Trigger
Working
BEAT2 theme (white/navy)
Prompt submit, tool use
Idle
Solid sunset mango
Claude finishes responding, session start
Needs input
Solid purple
Permission request, plan approval, question, notification
Off
LED off
Session end
There are a few caveats to this project. First, it seems to only work with Moonside lamps, with the Halo being the best choice. The creator does say it “should work with One, Aurora, Lighthouse, etc,” but it doesn’t feel like much of a guarantee. Also, the project page lists the compatible OSes as “macOS (BLE via CoreBluetooth),” so if you’re on Windows or Linux, you may be out of luck. Regardless, this is a really cool little project and a great way to keep an eye on Claude.
