Traffic Signals

EPA suspended the ENERGY STAR Traffic Signal specification effective May 1, 2007. In EPACT 2005, Congress passed a new minimum federal efficiency standard for traffic signals at the same level as the ENERGY STAR specification (and referencing the ENERGY STAR specification). All traffic signals manufactured on or after January 1, 2006 must meet these new criteria.
