visual alarms
Lights that warn
Visual alarms are warning signals that use light rather than sound—flashing strobes, blinking indicators, or color changes designed to alert people to emergencies, system failures, or other conditions requiring attention.
They're essential for deaf and hard-of-hearing individuals, and standard in environments where auditory signals might be missed: The building's fire system includes visual alarms in every room.
