Traffic Lights

A big classroom status display — red, amber or green, with an optional instruction underneath.

How to use
  • Click Red, Amber or Green to change the display — or use the keyboard shortcuts 1/2/3 (or R/A/G) at any time.
  • Type in the instruction box to change the text shown under the light for that colour — each colour remembers its own instruction, so switching back to red brings back your red text.
  • Click Hide controls — big display to clear the screen for a projector or whiteboard. Bring the controls back with the small Edit button in the top corner, or by pressing Escape.
  • Full screen uses your browser's full-screen mode for an even bigger, distraction-free display.
  • Your chosen colour and instruction text are remembered automatically on this device, so the tool reopens exactly as you left it.
