The DeKalb City Council adopted a three-year streetlighting plan Tuesday night.

The plan would replace a large portion of the present mercury vapor lights with sodium vapor bulbs on major DeKalb roads, the Muller/Rolfe/Park and Greek row neighborhoods the first year.

Continued relighting in the second and third years would be determined by the success of the first year’s plans.

The plan would also increase the number of lights in the residential neighborhoods listed where poor lighting is a problem.

Public Works Director Ronald Naylor said Commonwealth Edison will replace all 15-year or older bulbs at no cost to the city. Most of the bulbs in the designated areas are this old so costs would be nominal, he said.

There was some concern aout the efficiency of Commonwealth Edison. Sixth Ward Alderman James Pennigton said, “There are a lot of lights out there that are burned out and it is taking upwards of two months for these to be repaired.”

Naylor did not deny this but explained that it was out of his hands because Com Ed replaces bulbs on a part-time basis and has a four to six week backup.
