Which lighting marks the end of the runway you are facing?

• A. Runway End Identifier Lights (REIL)
• B. Threshold lights
• C. End of Runway Lighting
• D. VASI

Answer: (C)

Focus here is how runway lighting shows where the runway ends from the direction you’re facing. Threshold lights mark the beginning of the usable runway from the approach end, usually green to indicate “start here.” End-of-Runway Lighting, by contrast, marks the far end of the runway you’re looking toward, giving a clear boundary that you must not plan to land beyond. REIL lights are there to identify the threshold of the approach end, not to indicate the far end. VASI is a glide-slope indicator and isn’t used to mark runway endpoints. So the lighting that marks the end of the runway you’re facing is End of Runway Lighting.
