Runway edge lights are classified according to what characteristic?

Explanation:
Runway edge lights are classified by intensity because brightness is the factor that must be adjusted to match conditions and preserve pilot visibility. The lights along the runway edges can be set to low, medium, or high intensity, allowing for proper edge delineation in daylight, twilight, or low-visibility situations while avoiding excessive glare. Color is a fixed attribute for these lights and isn’t used to classify them, and frequency or size aren’t the basis for their grouping. The practical takeaway is that adjusting brightness ensures the runway edges remain clearly visible to pilots under varying conditions.
