The Wacker Neuson is a genuine OEM Light Bulb, S8, 12V, 21W, Ba15S designed for RD16-90 and RD16-100 tandem rollers as well as CB14B soil and asphalt compactors. As a factory-sourced replacement, this bulb matches the exact voltage, wattage, and base specification of the original component installed at the time of manufacture. Verified fitment spans multiple machine configurations across the RD16 and CB14B product families, so you can order with confidence that this is the correct part for your machine.
Key Features
- Exact Electrical Specification — S8 bulb format rated at 12V and 21W with a Ba15S single-contact bayonet base, matching the original circuit design of your machine.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this bulb meets the same output and longevity standards as the unit your machine shipped with.
- Drop-In Ba15S Base Replacement — The Ba15S bayonet mount seats and locks the same way as the original, making the swap straightforward without tools or adapters.
- Broad RD16 and CB14B Fitment — Confirmed for RD16-90 and RD16-100 tandem rollers across multiple build configurations, as well as CB14B-900 and CB14B-1000 soil and asphalt compactors.
- Restore Full Visibility on the Job — A burned-out work light leaves operators unable to monitor the compaction pass or work safely in low-light conditions; replacing it promptly keeps your crew operating as intended.
This light bulb serves as a work or indicator lamp within the electrical lighting circuit of your tandem roller or compactor. At 12V and 21W, it draws power from the machine's onboard electrical system and provides the illumination needed for low-light operation and visibility around the machine. When the bulb fails, the affected light circuit goes dark entirely, which can interrupt operations in early-morning, evening, or shaded jobsite conditions and may affect compliance with site lighting requirements. Replacing the 5000163221 with a correctly rated bulb restores the lighting circuit to its intended output immediately.
