Which item is typically maintained by linemen in a street lighting system?

Maintaining the electrical wiring, fixtures, and bulbs is essential for the proper functioning of a street lighting system. Linemen are responsible for ensuring that all components of the lighting system are in good working condition. This includes not only replacing burnt-out bulbs but also inspecting and repairing the electrical wiring that delivers power to the lights and the fixtures that hold the bulbs in place.

By keeping the entire system maintained, linemen ensure safety and visibility in public areas, making it crucial for their duties to encompass a comprehensive approach rather than focusing on just one aspect, such as the light bulbs alone. Other aspects of the street lighting system, like the decorative plants or traffic signals, may eventually relate to overall safety or aesthetics but fall under different maintenance responsibilities.
