The Multiquip 51908 is a genuine OEM 12 VDC Bulb designed for a range of Multiquip Mayco concrete pumps and RAMMAX walk-behind rollers, including the C30HDNI, C30HDN, LS40D, LS40TD, LS50TD, LS60TD, RW1810, RW1403HF, and RW1404MR (S/N 326075 and up). As a direct OEM replacement, part 51908 is sourced and validated to meet the original electrical specifications of these machines. Stocking this bulb as a service part keeps your equipment's indicator and warning light circuits fully operational without hunting for a cross-reference. DHS Equipment supplies this Multiquip OEM part with verified fitment so you can order with confidence.
Key Features
- Correct 12-Volt DC Output Rating — Matched to the original 12 VDC circuit voltage of compatible Mayco concrete pumps and RAMMAX roller models, ensuring proper lamp brightness and circuit load.
- Genuine OEM Part — Sourced directly from Multiquip, this bulb carries the same part number and electrical specification as the component installed at the factory.
- Broad Fitment Across Two Equipment Families — Confirmed fit for C30HDNI, C30HDN, LS40D, LS40TD, LS50TD, LS60TD, RW1810, RW1403HF, and RW1404MR (S/N 326075 and up).
- Drop-In Socket Replacement — Designed to seat directly into the existing bulb socket with no wiring modifications, making field or shop replacement straightforward.
- Maintains Indicator and Warning Light Function — A failed bulb can mask critical machine warnings; replacing with the correct OEM part restores full visibility of operational status signals.
- Electrical Safety Compliance — Using a bulb rated to the correct voltage prevents overloading the socket or wiring harness, protecting surrounding electrical components.
The 12 VDC Bulb in these machines serves the indicator and warning light circuits powered by the equipment's 12-volt DC electrical system. It provides the operator with visible status signals — such as running condition indicators or alert lights — that are essential for safe and informed machine operation. When the bulb burns out, those signals go dark, leaving the operator without critical visual feedback; replacing it promptly with the correct OEM-rated bulb restores full circuit function.
