City engineers redesigning streetlights for Fernhaven avoided a simple swap to brighter bulbs, arguing that excessive brightness increases glare without necessarily improving visibility. Instead, the new fixtures use adjustable LED arrays that dim automatically between midnight and five in the morning, when foot traffic drops, then brighten again as commuters return. Motion sensors embedded in each pole can also boost nearby lights temporarily when pedestrians or cyclists approach, a feature residents credit with making late-night walks feel safer. The redesign has cut the district's lighting energy costs by nearly a third, though several residents have complained that the dimming schedule sometimes activates too early on nights when local events keep streets busy well past midnight.
