Work on street lights is usually one of three activities:
Replace burn-outs. This is done on as needed basis. As they are reported they are replaced when timing and scheduling permits. This includes repair of defective luminaries, contractors or replacement of photocells.
Replace accident damage. This task is done as knock-downs are reported. This can also include contactor cabinets that have been hit by vehicles. It consists of replacing bases, poles, luminaries or contactor cabinets as required. Whatever is damaged beyond repair is replaced with new material. This work is usually done using contracted services.
Other general maintenance consists of painting cabinets or poles as required.
