Wacker Neuson 5000166678 Turn Signal Light

The Wacker Neuson is a genuine OEM Turn Signal Light designed for a wide range of Wacker Neuson indirect air heaters and hydronic surface heaters, including the HI 770 XHD, E1100, and Pureheat series. As a factory-sourced component, this part is manufactured to the exact specifications required by the original equipment, ensuring a direct, correct-fit installation. Whether you are servicing a diesel indirect air heater or a hydronic surface heater, this is the verified replacement part for your machine. Always confirm your model number before ordering to ensure full compatibility.

Key Features

• Genuine OEM Lamp Specification — Sourced directly from Wacker Neuson, this turn signal light meets the exact optical and electrical output specifications of the original unit — no guesswork on bulb type or lens fit.
• Drop-In Connector Compatibility — Designed to connect directly to the existing wiring harness on supported heater models, making replacement straightforward for field technicians.
• Broad Heater Family Coverage — Fits multiple configurations across the HI 770 XHD indirect air heater line, E1100 hydronic surface heater series, and Pureheat hydronic heater models in both diesel and gas variants.
• Keeps Tow and Transport Lighting Compliant — A functional turn signal is required for safe road transport of towable heater units; replacing a failed lamp restores proper signaling for legal trailer operation.
• Verified Part Number — Part number 5000166678 is the correct OEM reference across all compatible Arctic Bear XHD, HI 770 XHD, HP252, E1100, and Pureheat configurations listed in the Wacker Neuson parts system.

The turn signal light on a towable heater unit is a required safety and road-compliance component, providing directional signaling to other drivers when the unit is being transported between job sites. On indirect air heaters and hydronic surface heaters like the HI 770 XHD and E1100 series, which are frequently towed on public roads, a working turn signal light is essential for legal trailer operation and on-site safety. A burned-out or damaged turn signal can result in failed roadside inspections and creates a hazard during transport — replacing it promptly with the correct OEM part restores full compliance and visibility.
