Constructed with nickel-plated brass housing, a transparent polycarbonate lens (UL 94V-0), and robust terminals, these indicators are built for durability and longevity. They are suitable for instrument panels, safety systems, UL 508 panel applications, power generation, and transportation environments. The indicators feature a long lifespan (typically 100,000 hours), daylight viewability, and tamperproof design, making them a reliable choice for demanding industrial applications.
