What specific purpose do light wands serve in a work environment?

Light wands serve the specific purpose of communicating messages in a work environment. These devices are often used in scenarios where visibility is low or where verbal communication is not feasible. For example, they can convey important instructions or alerts, such as directing traffic, guiding workers in hazardous areas, or signaling emergencies. The use of light wands helps ensure safety and clarity in communication, facilitating better coordination among team members, especially in busy or dangerous work settings. Their bright, visible signals can catch attention quickly, reducing the chance of misunderstandings or accidents.
