, the applied LED technology specialist, now offers a flat and domed version of the successful 657 series panel-mount indicator. The new indicators feature a fully-sealed and potted design, making them impervious to dust and water intrusion and in compliance with IP67/NEMA 4X standards. Using the same high-impact, UV-stabilized lens material as the right-angle version, the indicators are available with tinted, diffused lenses in red, green, yellow, blue, and orange, in addition to a white diffused style to eliminate ‘phantom effect’ in outdoor applications. These rugged, daylight viewable indicators are engineered for outdoor applications such as lane control and signage, as well as construction, transit and military vehicles — anywhere that a vibration-resistant light source is required. The energy efficient LEDs used in these indicators provide up to 100,000 hours of operation, far exceeding the typical life of traditional light sources.
