Which color is the START VALVE OPEN alert light?

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

Answer: (A)

Color-coded alert indicators tell you how a system is behaving. Amber lights are used for advisory or caution conditions—signals you need to notice, but not a hard fault. For the Start Valve Open alert, the amber color means the start valve is currently open to allow starting air to flow to the pneumatic starter. This opening is part of the normal starting sequence and should occur briefly during start and then close as the engine lights off. If the light stays on after start or comes on for something abnormal, that would warrant attention. Green would indicate normal operation with no active start action, red would signal a fault or unsafe condition, and blue is used for other information not specific to this alert. So amber is the correct color.
