Warning lights are specialized lighting devices used for safety and alerting purposes in industrial, construction, and traffic control environments. They are often installed on machinery, vehicles, or road barriers to signal caution, indicate danger, or guide movement. Warning lights come in different colors (like red, amber, and blue) and may flash or remain steady to draw attention effectively. LED warning lights are commonly used due to their visibility, durability, and low power requirements, ensuring they remain operational in critical situations.
