New Jersey Statutes Title 27. Highways 27 § 1B-21.21

The commissioner shall install light emitting diodes lighting (“LED lighting”), or lighting similar in energy and life cycle savings, in traffic signals on the State highway system from the amounts appropriated from the revenues and other funds of the New Jersey Transportation Trust Fund Authority. It is anticipated that this lighting will result in operational energy savings for State, county and municipal governments and provide congestion relief because the diodes have a 10-year life cycle as compared to the one year replacement cycle for regular light bulbs. The State shall develop a program to assist local governments to install LED lighting or lighting similar in energy and life cycle savings, in approved local traffic signals throughout the State. The commissioner may consult with the State's public utility companies for assistance where appropriate to implement this program.
