Which exterior light is mounted on the vertical stabilizer?

• A. Red light
• B. White light
• C. Blue light
• D. Green light

Answer: (B)

Exterior navigation lights are arranged to show an aircraft’s position to others. The white light mounted on the tail, typically on the vertical stabilizer, is the one you see from behind. Red and green lights sit on the wingtips to indicate the left and right sides, respectively, so other pilots can tell direction. Blue isn’t used as a standard civilian tail light. So the light on the vertical stabilizer is the white tail light.
