What happens here

Understanding common failure points helps in diagnosing the problem more efficiently. Parking lot lights can fail due to several reasons, including severe weather conditions (like ice or extreme heat), ground freezing and thawing cycles affecting underground wiring, or physical damage to underground conduits.
