Dialight is the industry's acknowledged leader in LED-based traffic signals. These devices use 90 percent less energy and last 10 times longer than incandescent lamps. Our extensive offering ensures compliance with the latest ITE LED traffic signal module specifications including the ITE VTCSH - Circular Signal Supplement; ITE VTCSH – Part 3: LED Vehicle Arrow Traffic Signal Modules; and ITE PTCSI – Part2: LED Pedestrian Traffic Signal Modules; ITE VTCSH LED Vehicle Arrow Traffic Signal Supplement; Caltrans; and many other state and municipal DOT specifications. Products include red, yellow, and green modules using state-of-the-art, Hi-Flux LED technology; arrows; and a variety of pedestrian signals and countdown timers.

Dialight is the first manufacturer to offer a comprehensive line of LED traffic signal modules that are fully compliant to the new ITE specifications. Unlike other manufacturers whose LED yellow circular signals and yellow arrows can only meet the new ITE luminous intensity standards up to 25 °C, and therefore are non-compliant, Dialight offers LED yellow circular signals and yellow arrows that meet the new ITE luminous intensity standards up to 74 °C. In other words, Dialight offers LED yellow circular signals and yellow arrows that are compliant to the new ITE specifications, while the competitors referenced above do not!
