The work is part of a $4m effort to improve street lighting service in a number of communities this year.

DTE Energy will upgrade older street lights that are energized by series circuits, which pose problems because when one light goes out, other lights on the circuit can be affected.

The company is expected to begin work on other lights in March 2012.

The upgrades to high-pressure sodium lighting will improve overall reliability of the street light system in the community.

DTE Energy Community Lighting manager Ed Henderson said the work will reduce the number and duration of outages, use more energy-efficient fixtures and enhance public safety.
