The Wacker Neuson Bulb 12Vdc is a genuine OEM component designed for the LTS4K, LTS4Y, LTS7K, LTS8K, and LTS8L series light towers. Sourced directly from Wacker Neuson, this OEM bulb is built to the exact electrical specification required by these machines, ensuring correct voltage draw and light output every time. It is a direct drop-in replacement across multiple LTS configurations including 50 Hz and 60 Hz variants, Metal Halide and LED tower models, and both trailer-mounted and skid-mounted units. Cross-reference part number against your machine's model number before ordering to confirm the correct fit for your specific unit.
Key Features
- Correct 12Vdc Rating — Matched to the electrical system voltage of LTS series light towers, preventing under- or over-voltage conditions that can shorten bulb life or damage the lighting circuit.
- Genuine OEM Part — Supplied by Wacker Neuson as a direct factory replacement, so the output spec, base type, and physical dimensions are exactly what the fixture was engineered to accept.
- Broad LTS Series Compatibility — Fits LTS4K, LTS4Y, LTS7K, LTS8K, and LTS8L light towers across 50 Hz and 60 Hz configurations, covering both Metal Halide and LED tower models in trailer and skid-mount variants.
- Restore Full Illumination — A failed or dimming bulb reduces the working light area on site; replacing it with the correct 5100040966 restores the full rated lumen output the tower was designed to deliver.
- Electrical Safety Compliance — Using the specified OEM bulb maintains the correct load on the tower's electrical circuit, reducing the risk of overheating, blown fuses, or ballast damage caused by an incorrectly rated substitute.
The 12Vdc bulb in a light tower serves as the low-voltage indicator or auxiliary lighting component within the machine's electrical system, operating on the tower's 12-volt DC circuit rather than the high-voltage output circuit. A functioning bulb at the correct voltage rating ensures the circuit draws the expected current load; a failed or incorrect bulb can place unintended stress on fuses, wiring, or the ballast assembly. Replacing a burned-out or damaged bulb promptly keeps the tower's auxiliary systems operating as intended and prevents secondary electrical faults from developing.
