What color is the standard customer call light?

• A. Green
• B. Amber
• C. Blue
• D. Red

Answer: (C)

Color-coding of customer call lights is used to convey status quickly. The blue light signals a general request for assistance from a customer, prompting staff to respond with help or service. This color is chosen because it’s highly visible, stands out from red emergency signals, and is distinct from greens or ambers that might indicate other states, so staff can immediately recognize a routine help call without alarm. In contrast, red indicates urgent or emergency needs, amber or yellow flags attention or escalation, and green can denote that a request has been acknowledged or resolved. Keeping blue as the standard helps ensure consistent, prompt responses across the service area, even under different lighting conditions.
