visual alarm
Light-based warning signal
A visual alarm signals danger or alerts attention through light rather than sound.
Fire alarm systems include visual alarms—typically strobe lights—for deaf or hard-of-hearing individuals.
Security systems may use flashing lights alongside sirens.
Any warning device that operates by sight rather than hearing qualifies: The visual alarm flashed red when pressure dropped.
