In the notation 280 (L) 72, what does the letter L signify?

Explanation:
On aviation charts, letters in parentheses next to data indicate lighting or other operational features. The letter L specifically means Lighting in Operation from Sunset to Sunrise. This tells you that the associated lighting is active during night hours, so you can rely on it for nighttime operations. The numbers around it convey other data (distance, altitude, etc.), but the L itself is about when the lighting is on.
