Which lights are flush with the runway and emit a steady green color?

• A. Taxiway Edge Lights
• B. Taxiway Turnoff Lights
• C. Runway Edge Lights
• D. Approach Lights

Answer: (B)

In runway and taxiway lighting, color and placement tell you what to do. Lights that are flush with the runway surface and emit a steady green color are the taxiway turnoff lights. They mark the point where you can exit the runway onto a taxiway, guiding you off the runway without raising the lighting above the surface.

Why this fits: green is used to indicate movement on the surface and turnoffs, and being flush with the pavement keeps the exit path clear and easily visible as you decelerate and steer onto the exit. This distinguishes them from other runway or taxiway lights: taxiway edge lights are blue and run along the taxiway edges; runway edge lights are white (becoming red near the far end); approach lights extend outward from the threshold and are not on the pavement where you exit.
