Department of Transportation’s (DOT) lighting standards for commercial traffic and other motor vehicles place a priority on safety. For example, Standard 108 under Part 571 of the Federal Motor Vehicle Safety Standards and Regulations, which addresses vehicle lighting, states that its purpose is to “reduce traffic crashes and deaths and injuries resulting from traffic crashes, by providing adequate illumination of the roadway, and by enhancing the conspicuity of motor vehicles on the public roads so that their presence is perceived and their signals understood, both in daylight and in darkness or other conditions of reduced visibility.”
The American Association of Highway and Transportation Officials (AASHTO) extends the DOT’s safety standards into highway and roadway lighting, and incorporates elements of environmental management and sustainability into lighting standards for highways. In all cases, LED highway lighting is the ideal solution to satisfy these and other concerns.
Highway authorities and municipalities can also achieve substantial operating and maintenance cost savings with LED highway lights. Initial installation and retrofitting costs will be recouped within one to two years from reductions in electrical power consumption. Most next-generation LED highway lighting systems consume less than half the power as halogen or high pressure sodium fixtures while generating the same or better illumination. New LED fixtures also last more than five years, and in many cases up to ten years before requiring replacement. Modular engineering makes it possible for technicians to replace fixtures that are damaged by vehicle accidents or extreme environmental conditions without affecting other fixtures. In most cases, advances in LED technology, including sealed fixtures and housings and advanced thermal management mechanisms, have made it possible for LED fixtures to continue operating regardless of extreme heat, cold, precipitation, and other environmental stresses.
