Signal towers/stack lights are commonly used on equipment in industrial manufacturing and process control environments to provide visual (audible on request) indicators of a machine state or process event to machine operators, technicians, production managers, and factory personnel.
Stack lights are used in a variety of machines and process environments. The three basic color codes for machine state conditions include:
RED – failure conditions such as an emergency stop or machine fault.
YELLOW – warnings such as over-temperature or over-pressure conditions.
GREEN – normal machine or process operation.
This Red-Yellow-Green Folded signal lights LED Tower has an aesthetic design, high brightness LED chip, wide-angle, low thermal resistance, concentrated color area, low brightness decay with a long lifespan, and buzzer (volume louder than 85dB). The structure of the design provides good heat dissipation. The layout of internal electronic components provides high efficiency.
