3-colour traffic light via XLR cable

The 3-colour traffic light is intended for use in the conference room environment to signal to the speaker at a lectern. When timings are important, the speakers can be informed when their time is short (green for ok, amber for 10minutes, red for finish soon, for example) . The LEDs can be continuous or blinking and a mimic LED is incorporated in the control unit. The principle can be used in other environments.
