Extra lighting has been added to some convenience centers in order to improve the diminished natural light in the evenings.“On the lighting situation, I checked on the cost,” said Warren County sanitation director Steve Hillis to members of the county Health and Welfare Committee on Monday.Last month the county received complaints the time change has created diminished lighting at the convenience centers in Viola and Smartt Station. The problem begins with the end of daylight savings time in November and ends with its beginning in March. At that time, Hillis said the situation is a pole problem that could be improved if the short poles where the lights are located are exchanged for taller poles.“Most of our convenience centers are the same,” he said.
