The Wacker Neuson 12 Vdc Horn is a genuine OEM audible warning device designed for RD27-100 and RD27-120 series hydrostatic vibratory rollers. As a direct OEM replacement, this horn is sourced and manufactured to the same specifications as the original unit installed at the factory, ensuring a direct, hassle-free swap into your RD27 roller. Fitment covers multiple RD27-100 and RD27-120 configurations, including standard and traction control variants across a wide range of serial number ranges. Keeping this component in proper working order is essential for safe machine operation on active job sites.
Key Features
- OEM-Matched Voltage Rating: — Engineered to operate at 12 Vdc, matching the electrical system of the RD27 roller series for correct output and consistent sound performance.
- Direct-Connect Replacement: — Designed to mount and wire into the existing horn circuit on RD27-100 and RD27-120 rollers without modifications to brackets or wiring harnesses.
- Broad RD27 Fitment: — Compatible with standard and traction control variants of the RD27-100 and RD27-120 hydrostatic vibratory roller across multiple machine configurations.
- Audible Warning System Integrity: — A functioning horn is critical for alerting ground personnel around a moving roller; a failed horn leaves operators unable to signal in proximity-critical situations.
- Safety-Critical Compliance: — Audible warning devices are required on powered rollers operating in traffic control zones and confined work areas; this OEM part restores that compliance immediately.
The horn on a vibratory roller serves as the machine's primary audible warning device, allowing the operator to alert ground crew, pedestrians, and other equipment operators of the roller's movement or presence. On large tandem rollers like the RD27 series, where forward and reverse passes are frequent and visibility around the drums can be limited, a working horn is a fundamental safety component. When the horn fails, the machine loses its ability to signal in proximity-critical situations, which can create hazardous conditions on active paving or compaction sites.
