By the end of next week the conversion of some 1,675 old sodium-vapor and mercury-vapor street lights in Ypsilanti to LED's should be complete.  Not only will the conversion make city streets brighter and safer, it will also save the city about $120,000 a year.

That's according to City Manager Ralph Lange, who says DTE Energy has 119 post-top lights left to convert. 

Lange says the conversion project cost less than $600,000.
