Runway guard lights are which color and where are they installed?

• A. Red obstruction lights
• B. White runway lights
• C. Elevated flashing yellow lights
• D. Green taxiway lights

Answer: (C)

Runway guard lights are the amber, flashing lights placed at the boundary where a taxiway meets a runway. They’re elevated on posts so they’re clearly visible to both pilots and ground vehicle operators, signaling that an active runway is ahead and caution is required before crossing or entering. This makes elevated flashing yellow lights the correct description. Red obstruction lights are used for tall or hazardous obstacles, white runway lights belong to the runway itself, and green taxiway lights mark the taxiway path, not the boundary warning.
