Stop watching the tab. Watch the signal.
PromLight turns agent progress into a physical cue that sits in peripheral vision, so background coding work is easier to notice without constant context switching.

Green steady tells you the agent finished.
Small hardware for a very specific workflow
The source material describes a 25 x 67 x 21 mm rechargeable Bluetooth light with a clip, elastic strap, top power button, and bottom USB-C charging port.
Bluetooth 5.3
Rated for about 20 m effective distance in open conditions.
400mAh battery
About 4 to 5 days at 8 hours per day, based on source material.
USB-C charging
USB-C is for charging only. The computer link is wireless.
Windows and macOS
Linux, phones, and tablets are not currently supported.
A quick local setup before real work
The light depends on Bluetooth pairing and a desktop app that watches agent hooks. Test the chain before relying on it during a long run.
Charge it
Use the USB-C port and place the light where it is easy to see.
Pair it
Connect over Bluetooth from the PromLight desktop app.
Bind hooks
Map AI agent events to busy, waiting, error, and complete states.
Test signals
Run manual commands before trusting it in a real session.
Compatibility is clear before checkout
The listing evidence is useful but bounded. The site repeats those boundaries rather than adding unsupported platform, certification, or privacy claims.

Not claimed from current evidence
- No CE, FCC, RoHS, waterproof, or drop-resistance claim is made from the provided material.
- No maximum multi-device count is stated, even though multiple lights are listed as supported.
- No Linux, phone, or tablet support is claimed.
- No offline-only or cloud-free claim is made without stronger proof.
Built around real hook feedback, not another dashboard
The captured control panel shows device state, direct light controls, hook logs, and manual commands. The physical light is the output you can notice away from the browser.
Device list
The captured control panel shows connected PromLight units.
Light controls
Per-light controls can switch red, yellow, and green states.
Hook logs
Event logs help debug why an agent state changed.
Manual commands
Manual testing is available before live workflow use.
Questions to answer before you order
PromLight is simple hardware, but compatibility and setup expectations matter. These answers only use claims supported by the provided material.
Read the setup guideWhat is PromLight AI Signal Light?
PromLight is a rechargeable Bluetooth desk light for AI coding-agent workflows. It turns background agent states into red, yellow, and green physical signals so you can step away from the screen without missing important state changes.
Which AI tools does it support?
The source material lists Claude Code, Codex, Cursor, Copilot, and Qoder. Do not assume every version or every third-party fork is supported until the desktop app confirms it.
What do the light states mean?
The listed mapping is yellow steady for busy, yellow blink for waiting for confirmation, red blink for error, and green steady for complete.
Does USB-C connect the light to the computer?
No. The USB-C port is for charging only. The computer connection is wireless over Bluetooth.
How far can it work from the computer?
The product material lists about 20 m effective distance over Bluetooth 5.3. Real-world range can be lower when walls, furniture, metal surfaces, or wireless interference are present.
How long does the battery last?
The source material lists a 400mAh lithium battery rated for about 4 to 5 days when used 8 hours per day. Actual runtime depends on brightness, blink patterns, and connection behavior.
Can one computer connect to multiple lights?
The source material says one computer can connect to multiple PromLight units. It does not provide a reliable maximum count, so the site does not claim one.
Does it work on Linux, phones, or tablets?
The listed platform support is Windows and macOS. Linux, phones, and tablets are not currently supported by the source material.
Does the desktop app need to stay open?
The source material describes a PC program designed to run in the background and start with the computer. The light depends on that local app for agent status mapping.
What does the control panel do?
The captured control panel shows a device list, per-light controls, event or hook logs, and manual command controls.
How does it mount on a desk or monitor?
The product material shows a back clip and elastic strap. That supports simple placement on a desk setup, but buyers should confirm their exact mounting surface before relying on it.
How big is the light?
The listed body size is about 25 x 67 x 21 mm, compact enough for a monitor edge, desk shelf, or nearby stand.
Does the product need cloud access?
The provided material proves Bluetooth hardware and a local control panel, but it does not prove a no-cloud design. The site therefore avoids claiming offline-only or cloud-free behavior.
Is it CE, FCC, or RoHS certified?
The provided source material does not include certification proof, so the site does not claim CE, FCC, RoHS, waterproofing, drop resistance, or similar compliance properties.
What is included?
The source material clearly shows the PromLight device and a charging cable. It also shows clip and strap mounting hardware. Any bundle-specific extras should be confirmed at checkout.
Who is it for?
It is for developers, builders, and AI-heavy operators who run coding agents in the background and want a physical signal for work that is busy, blocked, errored, or complete.
