Wacker Neuson 5000163222 Light Bulb, T3-1/4, 12V, 5W

The Wacker Neuson is a genuine OEM Light Bulb, T3-1/4, 12V, 5W designed for the RD16-90, RD16-100, and CB14B series tandem and vibratory rollers. As a factory-sourced component, this bulb is produced to the exact voltage and wattage specifications required by Wacker Neuson, ensuring a correct, direct swap into the original lamp socket without guesswork. It is confirmed compatible across multiple configurations of the RD16-90 and RD16-100 tandem rollers — including hydrostatic variants — as well as CB14B soil and asphalt compaction machines. When the original bulb burns out, replacing it with the genuine Wacker Neuson restores full lighting function quickly and with confidence.

Key Features

• Matched Voltage and Wattage: — Rated at exactly 12V and 5W to match the electrical system of the host machine, preventing under-lighting or premature burn-out caused by mismatched specs.
• T3-1/4 Bulb Form Factor: — The T3-1/4 tubular envelope seats directly into the OEM lamp housing with no socket modification, making replacement straightforward in the field.
• Genuine OEM Sourcing: — Produced by Wacker Neuson as an authorized factory part, delivering the same service life and luminous output as the bulb installed at the factory.
• Broad RD and CB14B Compatibility: — Fits RD16-90 (standard and hydrostatic), RD16-100 (standard and hydrostatic), and CB14B-900 and CB14B-1000 configurations used in soil and asphalt compaction applications.
• Restored Operator Visibility: — A functioning instrument or work light is critical for safe low-light operation on compaction equipment; replacing a failed bulb promptly keeps the operator informed and the work area properly illuminated.

The Light Bulb, T3-1/4, 12V, 5W serves as the light source within the instrument panel or auxiliary lighting circuit of the roller. It draws power from the machine's 12-volt electrical system and converts it to visible light, allowing operators to monitor gauges and controls in low-light conditions or enclosed environments. When the filament fails, the associated indicator or work light goes dark, potentially obscuring critical machine status information and creating unsafe working conditions — making timely replacement with the correct part essential.
