AI Overview
3-color signal indicator lights (red/yellow/green) provide visual status cues for industrial machinery, traffic control, and automation. These LED lights often feature durable housing (IP55/IP65 rated), operate at 12-24V DC or 110-220V AC, and include options for steady or flashing modes. They are used for signaling, such as on AliExpress and Amazon.
