Finlandia / Harvia Part # F42 Indicator Light (Red Color) gives you a clear, instant visual cue that your sauna heater is energized, adding an important layer of safety and convenience to your control panel. Designed for seamless use with Finlandia and Harvia control systems, this red pilot light illuminates whenever the heater is operating, making it easy for staff or homeowners to confirm status at a glance, even across the room. The lens and body are built from heat-tolerant, sauna-ready materials that stand up to elevated temperatures and humidity without fading, cracking, or loosening over time. Its compact form factor drops into the designated panel opening for a clean, professional appearance. Ideal for new installations or as a replacement for a failed or dim indicator, the F42 helps keep sauna operation transparent and well monitored.
