The Wacker Neuson Working Light is a genuine OEM Working Light designed for the RD40-130 and RD45-140 tandem roller series. As a factory-sourced component, it meets the exact output and fitment specifications Wacker Neuson built into these machines. This part covers a wide range of RD40-130 and RD45-140 variants — including C, O, US, DPF, and.3 configurations — so you can order with confidence that is the correct replacement for your roller. Sourcing direct OEM ensures the lamp housing, connector, and light output match the original installation precisely.
Key Features
- OEM-Rated Light Output — Manufactured to the same luminosity and voltage spec as the original, so operators get consistent, dependable illumination on every shift.
- Direct Drop-In Replacement — Connector and mounting points match the original housing exactly, so the light seats and secures the same way the factory unit did.
- Broad RD-Series Coverage — Fits RD40-130 and RD45-140 variants including C, O, US, DPF, and .3 builds across multiple serial-range groups — one part number serves the full family.
- Sustained Visibility Under Working Conditions — A properly functioning working light keeps the drum path and surrounding grade clearly visible during low-light paving and compaction operations; a failed light forces work stoppages or creates unsafe blind spots.
- Electrical Safety Compliance — Genuine OEM construction ensures the unit meets the original wiring load and housing seal requirements, preventing shorts or moisture ingress that an undersized replacement can introduce.
A working light on a tandem roller illuminates the area directly in front of or behind the drums, giving operators a clear view of the compaction surface during early-morning, late-evening, or shaded jobsite conditions. It is wired into the machine's electrical system and controlled from the operator station, and its housing is designed to withstand the heat, vibration, and debris exposure typical of roller operation. When the light fails — whether from a blown element, cracked lens, or damaged connector — visibility drops and work must slow or stop; replacing it promptly with the correct OEM part restores full operational capability without introducing compatibility risk.
