Abstract

This article describes how light-emitting diodes (LEDs) have been appearing in traffic signals and vehicle headlights for years. LEDs are considered to be another source of light used to navigate through cities and towns. Municipal street lighting retrofitted with LEDs has enhanced several communities' nighttime environments, while significantly reducing energy consumption and maintenance costs. Administrators are well-versed in the financial strains of street lighting. It can account for up to one-quarter of a municipality's electric bill, while maintenance cost account for another 15 to 25 percent of the annual operating expenses. The article shows how the use of LEDs can drastically reduce energy costs.
