A Desk Status Light That Tells Coworkers to Wait
Status Light costs $45. A matte-black case holds a vertical traffic-signal arrangement: green is lowest, amber occupies the centre and red is highest, each behind a domed lens. That visible form could support a shared-office signal, but the catalogue does not confirm a control API, connection or programmable lighting behavior.
Can one light serve you and your coworkers at once?
Only with an agreed source of truth. A light might represent the operator's availability, an agent state or a manually selected signal, but combining those meanings can confuse people. “Agent is working” does not always mean “do not interrupt.”
Choose one purpose and write it down. The software state must remain available separately in case the lamp, adapter or automation is stale.
Why does red-amber-green work without a legend?
The sequence is familiar, yet meanings vary by context and colour perception. Red may mean busy, error or stop; amber may mean waiting or warning; green may mean available or complete. Coworkers still need a short legend and a non-colour cue when accessibility matters.
Never use colour alone for a security or approval decision. A label, screen state or message should carry the authoritative information.
What do you have to set up to drive it?
First verify whether the unit can be controlled at all, how it connects and what current documentation supports. Then identify a reliable software event source and a small adapter that fails visibly. Polling a guessed state or scraping terminal text can leave the wrong lens lit.
Test startup, sleep, lost connection and process failure. Provide a manual off control and avoid storing credentials in a lamp script.
What are the limits of a three-lens lamp?
Three colours cannot explain which task needs attention, whether a result passed review or who owns the next action. The light may also be outside a coworker's sightline or distracting in a quiet room. It is a summary, not a dashboard.
The Status Light should be purchased for its confirmed physical design only after control behavior is documented. Treat the coding agent's own interface as authoritative and keep office meanings simple, accessible and reversible. Ask the team before installing a shared signal. Document who can change it, how long a state remains valid and what to do when it disagrees with the screen. Turn it off outside working hours and avoid brightness assumptions until the real unit is evaluated. A considerate office indicator is quiet, comprehensible and easy for others to ignore when it is not relevant. Place it outside direct glare and do not infer visibility from a product photograph.
