The Wacker Neuson Pilot Light is a genuine OEM component designed for the HSH hydronic surface heater series, including the HSH700, HSH350, HSH650, HP252, and E700M models. As a factory-sourced replacement, it matches the original specification exactly, ensuring proper fit and function without any guesswork. Whether you're servicing a unit on a winter concrete pour or maintaining a fleet of surface heaters, this is the correct part to restore your indicator circuit to full operation.
Key Features
- Correct Voltage and Lamp Specification — Manufactured to the original electrical rating, so the indicator illuminates accurately without risk of premature burnout or dim output.
- Direct Drop-In Replacement — Matches the original mounting footprint and connector configuration of the HSH series panel, allowing a straightforward swap during routine service.
- Broad HSH Series Compatibility — Confirmed fitment across the HSH700, HSH350, HSH650, HP252, and E700M hydronic surface heaters, covering both 50 Hz and standard configurations.
- Operational Status at a Glance — A functioning pilot light gives operators an immediate visual confirmation that the heater is energized, supporting safe and efficient jobsite use.
- Genuine Wacker Neuson OEM Quality — Sourced directly through the Wacker Neuson parts network, carrying the same part number — 5000172037 — as the component installed at the factory.
The pilot light on a hydronic surface heater serves as the primary visual indicator that the unit is receiving power and is in an active operating state. Located on the control panel, it gives operators an instant confirmation of system status without needing to inspect internal components. When the pilot light fails or burns out, it removes that critical at-a-glance signal, making it harder to verify whether the heater is running — particularly important in low-visibility or high-activity work environments where safe operation depends on clear status monitoring.
