Navigation Lights

• Red and green position lights on the wingtips and tail.
• White strobe lights on the fuselage.

Anti-Collision Lights

• Rotating beacon on the tail.
• Flashing strobe lights on the wingtips.

Landing Lights

• Forward-facing lights that illuminate the runway.

Taxi Lights

• Downward-facing lights that illuminate the ground around the aircraft.

7. How would you diagnose and repair a faulty aircraft instrument?

• Check the instrument’s power supply and wiring.
