Which indicator light signals Smoke in lavatory?

• A. Blue Ceiling Indicator Light
• B. Amber Ceiling Indicator Light
• C. Pink Ceiling Indicator Light
• D. Flashing Amber Ceiling Indicator Light

Answer: (D)

Indicator lights in the cabin use color and flash patterns to convey lavatory status and emergencies. When smoke is detected in the lavatory, the system activates a flashing amber ceiling light to grab attention and prompt crew action. A blue ceiling light usually means the lavatory is occupied, not an alarm. Pink is used for other non-smoke alerts, and a steady amber light signals a non-urgent caution rather than an active smoke condition. Therefore, the flashing amber ceiling indicator light correctly signals smoke in the lavatory.
