LED lights: Going "green" causes unintended problem for public works crews in West Bend - WITI OK, So they save the city $100 per month at each intersection. $2400 total for the intersections. $28,800 per year. BUT it costs the city to have four, 2 person crews scrape the ice and snow from the lenses each snowstorm. I gotta think that the cost of these 8 guys doing this job during the winter months costs more than $28,800. Not to mention the traffic accidents that were caused by the lights. Hey, I have a solution. Put the old ones back up.
